Debian Multimedia :: Alsa, Pulseaudio, ION2 & HDMI Sound Output?
Apr 29, 2011
I have recently acquired a Lenovo Q150 machine and attempting to use it as a HTPC. I've been reading that with this platform a newer kernel is required to make wireless, sound and a few other tweaks work correctly--so I bumped up to testing repositories to upgrade to the 2.6.38 kernel.[URL]...
The audio on this device has been more than a pain. I'm currently using XBMC to play media on this device and after setting the outputs to custom: plughw:1,9 sound is played correctly. I found this out by using alsamixer, selecting the sound card with the F6 key (Nvidia 1) unmutting all outputs, quiting, and running speaker-test -D plughw:1,X where X is the sub-device from the output of aplay -l until sound could be heard from the receiver.
Now my problem is that applications like mplayer, and iceweasel won't output any sound. I'd prefer not to use the optical out on the device and would like to send sound over HDMI. Has anyone had any luck getting it to work as it should?
I've also installed pulseaudio, not too sure if this is really needed. I've also used module assistant before upgrading to compile alsa from source, it worked but i just decided to upgrade the kernel instead of dealing with m-a every time an update comes through.

I have a Giada Slim-N20 running XBMC-Live 10.1 (Ubuntu v.10.04.1). It is hooked up by HDMI to my two-speaker TV. I don't think XBMC is my problem, however. Out of the box, XBMC supports sound over HDMI (if you tell it to use it), but when I try to run ZSNES, I only get sound through the headphone jack on the side. Now, the one problem with XBMC is that menu sounds go through the default device (i.e. the headphone jack) rather than the device selected in its settings (in my case, the HDMI port). In order to fix that problem, my .asoundrc looks like this:
Code:
pcm.!default {
type plug
slave {
pcm "hw:1,3"
}
}
Unfortunately, this does not fix ZSNES for some reason. Even worse, I no longer get sound through the headphone jack. What does fix ZSNES, however, is this strange hack that has been making the rounds on the XBMC forums. First, you download a modified version of HDA-Intel.conf found here. It appears to route everything through pcm.!remap-surround71. Then, you use this asound.conf:
Code:
pcm.!hdmi-remap {
type asym
playback.pcm {
[code]....
This almost fixes everything. Unfortunately, when I try playing a video with AC3/Dolby Digital, I get a screechy, garbled mess. Videos with mp3 and DTS work fine, however. what the asound files or the modified HDA-Intel.conf are trying to do. My guess is that something with the 7.1 mapping is screwing up AC3. And my hunch is that such a hack is way too complicated just to tell ZSNES to use the HDMI port. And, yes, ZSNES is instructed to use SDL or ALSA (neither appears to make a difference).

I am using a couple of Debian Distro (Sid and Lenny) add some Ubuntu into the mix. I made the switch because I was amazed and satisfied with Debian --> once installed, everything works. For me that's okay for o so many years now. I don't question a lot because it just works and I do my job on it satisfactorily. Namely programming the LAMP style programming. Lately I have been using Debian to communicate over the internet -- using Skype and Pidgin and other such things, not to mention listening to music, watching movies, just using the default applications when I originally install Debian.
Along the way, I need to configure something -- that is desktop related -- like the screen resolution of a new LCD monitor replacing the old one and such. Now about my sound -- I'm not touching it because it is working. But that is not the case always. Now I have a constant error -- it is irritating. Rhythmbox don't make a sound always when I have open a web browser (iceweasel, chrome, epiphany) and a site with multimedia object on it -- like a video or something. So how do I correct this? How do I know, too what I am using -- ALSA or Pulseaudio?

I spent a few days trying to make audio work on my TV connected via HDMI to a PC. The speaker test used by the sound preferences was dead, as was MPlayer. I managed to find a solution for MPlayer, giving the option "-ao alsa:device=hdmi", as specified in this article:So, basically ALSA can see all my devices. This is the output of aplay -l:Quote:

Running 10.10 and win 7 on my HP dv6-2150us laptop and I'm having a few issues.
First how do I get HDMI audio output to my TV? I think I have just a integrated Intel graphics card. It works fine in windows but I can't seem to get it to work in Ubuntu. I tried searching but couldn't find anything pertaining to this issue.

Having some problems with HDMI-Audio on my HTPC: I don't get sound out of HDMI port! For system info look there: Sysprofile
OS is Suse11.3 64Bit with KDE now!
At "System-Settings/Multimedia/Audio Output" there are the following devices in the given order:
HDA NVidia (ALC662 rev1 Analog)
HDA NVidia (ALC662 rev2 Digital)
HDA NVidia, NVIDIA HDMI (HDMI Audio)
That's consistent with the connector layout of the mainboard. Playing "Test sound" while marked the HDMI Audio is not causing any output with HDMI, while analog works just fine!
I also installed the nVidia prop drivers with the packet manager.
In YAST there is one card found in the sound section::
Idex=0 and Card Model=MCP79 High Definition Audio

I recently got a new ATI HD 4890 graphics card that supports sound over HDMI. It works in my other OS (Windows 7) but I cannot get it to work in Xubuntu. I read somewhere that by default the open source drivers have HDMI sound disabled. How do I turn it on? I even tried the Comprehensive Sound Problems Solutions Guide and still have no sound.

I am attempting to set up a machine to use as a movie/video viewer. When I connect this machine using an HDMI cable to an HDMI TV, I get video, but no audio. No beeps, no system sounds, no noise of any kind.
I've run the following mixers and set all volume controls to maximum:Gmixer, Kmix, AlsaMixer and pavucontrol.
When playing a video, pavucontrol meter shows signal from the application and shows output signal to the HDMI device, but where that output is going to is beyond me.
Using the Sound setup of Yast, I attempt to play a test sound on the HDMI, nothing.
Built in Audio adapter works fine. I have disabled it in pavucontrol in attempts to get the sound directed to the HDMI output, but, silence is all I get. I've also tried enabling and disabling simultaneous output with no difference in results.
I've tried a few suggestions from other posts with the same issue (creating /etc/asoundrc.conf, modifying /etc/pulse/default.pa), but no joy.
If I boot up that other operating system (starts with a W), all sounds (system & video) show up on the HDMI input with no adjustments needed.
Why must this be so difficult?
The technical details:
Suse 11.4
EVGA GeForce 8400GS Video card (HDMI)
All commands below were issued while HDMI cable connected, and video playing (using VLC).

I just got the upgrade for the Linux Kernel version 2.6.40-4 on my Fedora 15 x86-64 box today, and the installation completed with no problems. However when I rebooted after doing the upgrade, I noticed that I had no sound. I use an ATI Radeon HD 4350 video card, and the opensource ATI driver, and use the HDMI audio from it for sound, since my monitor has a sound output jack on it. I've booted into the previous kernel (2.6.38.8-35), and sound works fine. I've tried with the new kernel in both KDE (my default desktop environment) and XFCE to get sound, and it does not work in either one. I've tried installing the VLC Phonon Backend instead of the GStreamer Backend, reinstalling Pulseaudio, reinstalling Alsa, modprobing the necessary modules needed for the card, checking all configurations with the available Pulseaudio tools (paprefs, pavumeter, pavucontrol), checked the volumes using alsamixer, and reinstalling the ALSA Pulseaudio plugin. After trying all of these, I can still get no sound out of any application, and I also noticed that Flash video plays at 2-3 times it's normal speed after the upgrade. Again, these problems do not occur on my previous kernel. Did I maybe overlook something, or can anyone else think of something I could try?

When I installed my 64 bit system of Ubuntu 10.04 the sound worked very well and I were very happy. The problem started however when I installed Skype which uses pulseaudio. As soon as I start skype (or any other application that uses pulse, HoN for example) the applications sound output or input does not work at all. If I have pulseaudio started in some way, applications that I suppose do not use it like spotify or flash player stops to produce sounds. And when I type "pulseaudio" in the terminal it gives me this:

I'm on Jessie, and use KDE.
Sound keeps coming from laptop's speakers, even when HDMI is connected to an external TV.
I've tried to fix this issue using both Pulse Audio Volume Control and KDE's System Settings -> Multimedia -> Audio and Video Settings. No luck. I've read several topics around, but there are plenty of variables to consider.

Regarding ALSA and PulseAudio - Explanation on how these two interact. After installing Debian I realised that my sound control (Volume Control: HDA Intel ALSA mixer) was different from what I had with Ubuntu where it would display a window called "Sound properties" in which allowed me to control the sound of each program running - I believe this is the PulseAudio aspect. (If I'm wrong at this point please correct me)
Now I have managed to get PulseAudio setup correctly for me (not as easily as Ubuntu but I moved to Debian to learn, not be spoon fed), however the way in which I did it may of been wrong - pretty much just went to synaptic and installed everything with PulseAudio in its name
Currently the sound icon in my top Gnome panel (within the notification area applet) has the ALSA mixer, sometimes when I log on it has the PulseAudio one (Sound preferences window), I don't really mind which one is loaded thanks to the PulseAudio Volume Control program (under Sound & Video). Is there a way though to stick with just one?

I've had nothing but trouble with Pulseaudio in Fedora 14. I had managed to get rid of it in Fedora 10 with the command: su -c "yum remove alsa-plugins-pulseaudio pulseaudio" I just don't want to have to deal with Pulseaudio anymore. It does not like my sound card and gets in the way. Is there a Linux distribution that does not use Pulseaudio ?

In the process of trying to get the softmodem working, I finally attached speakers to this laptop and tried to play some sounds. Nothing but silence. Both the KDE system sounds and a stand-alone player (noatun) produce nothing. No error messages that I can find, either. (That might explain why the softmodem is dead, too...) I've run alsaconf several times, and even uninstalled and reinstalled ALSA. It thinks it is working, but is not. What sorts of things do I need to check to find where it isn't working?
Info: The motherboard is a FIC 3500W with the VIA P4M800 integrated chipset. This includes the VIA 8237 sound system, which is what ALSA detects and tries to use. The machine also has a Realtek ALC655 but I don't see any drivers for that in the lsmod output, so this is a possible source of the trouble.

I decided to break free from the horrible life of a windows vista user. I like my new debian (Wheezy) installation and everything worked fine so far. Now I stumbled upon a huge problem. When I want startup and login into my gnome installation the first application I open gets to play sound and others after that just don't work. I looked endlessly on google but in my understanding the problem is within the ALSA driver.
Some specs :
OS version : Debian 7 (Wheezy)
Laptop brand : Packerd Bell Easynote LJ-65
Kernel installed : 2.6.38-2-686 (Standard one in wheezy)

i am having a problem with skype that i wasn't having before, and afaik skype hasn't been upgraded recently, so something else presumably has changed.
because of driver issues i have to use an external usb audio interface to do voip. this interface is not connected to the pulseaudio server. i am able to connect it to jackd and it works fine for both audio in and out. however it no longer shows up in the list of sound devices available to skype. this used not to be the case. i have tried stopping and restarting skype, as well as unplugging and reattaching the interface. the interface does not show up in pulseaudio manager in the lists of devices.

i am using ubuntu 10.04 lts "lucid lynx", and has been encountering problems with audio recently.
i found out for some reason that my system fails to produce sound through pulseaudio, especially when an application is using it (e.g audacious).
the details of the problem:
1. i am using the pulseaudio equalizer from the repository, and i set a program (e.g. audacious) to use pulseaudio so that i can activate the equalizer.
2. while playing, all of my other applications lose the ability to produce any sound, and changing back to alsa during playback (which is using pulseaudio) in audacious indicates that the device is busy. examples include the loss of sound while playing a video from videos.
rough breakdown of what i want to (be able to) do: have sound for all applications using it, for example being able to play a video in videos from my browser and play music in audacious simultaneously.
is there a workaround for this? i'd like to think that there is, but so far my search returned nil.

I'm under Ubuntu 8.04 LTS Hardy Heron using pulseaudio. I've got 2 soundcards : one internal AC97 7.1 without midi (card 0 in ALSA) and a PCI C-MEDIA 2.1 with OPL3 midi (card 3 in ALSA) I have sound in most ALSA or OSS applications with full 7.1 + 2.1 duplex. I have MIDI playback in any ALSA MIDI players (client 29:0 in ALSA).
I'm trying to run Final Doom for W95 on WINE with OSS driver. I have sound effects but no MIDI music. I tryed with padsp and aoss wrappers. I know I can use ALSA driver in wine or timidity, but I would rather use padsp + hardware MIDI if possible. How do I configure ALSA OSS emulation for MIDI playback and check that it's working ? I tryed playmidi but whatever I told it, it couldn't find any midi device.

It was recommended to me that I remove pulseaudio and re-install alsa. All the howtos on reinstalling alsa had instructions for re-installing alsa from the source. Is it possible to re-install alsa from the repos? If so what are the necessary packages that I need to install, for a complete re-install of alsa?

I've recently switched to Debian Squeeze x64 from Kubuntu 10.04 x64. Overall, I like Debian.
I have one small problem: I play Runescape occasionally, which requires Java. On Kubuntu, I'd use Sun Java, however on Debian it just crashes.
So, I decided to use OpenJDK. Now OpenJDK works fine... But I can't get it to work with ALSA audio output. I installed PulseAudio, and that took care of -that- problem.
Now, currently I have both ALSA and PulseAudio installed. For playback, it works great. PulseAudio is a bit laggy, which isn't too noticeable in Runescape, and for things like media, it seems to work OK. For TF2, which I play through Wine however... No. So, I set that to ALSA, and -that- worked right.
Now comes my main problem: I can't get mic input. I'm trying to use Teamspeak 3(proprietary), and while audio output works, I can't get any input.
TS3 lets me use ALSA or Pulse(along with a couple more), but:
1. Selecting PulseAudio lets me select "SB Audigy Analog Mono", the same thing but a "monitor", and "Default Input Device". None of those work, I get "Error: could not open the selected capture device". On top of that, in the PulseAudio control panel, I get zero level on the monitor, making me think its not setup correctly.
2. Selecting ALSA gives me a whole list of options... But they appear to be audio -outputs-, not capture devices. Also, I get the same error as above.
When running "arecord -l", I get:
Of these, I believe the first one was what worked on Kubuntu. Now, of note is that I'm using my "Line in 2" port for capture; On my previous installations I'd simply set its volume with alsamixer and be done with it.
That all being said, I need a solution to one of these three problems:
1. How can I get OpenJDK to work with ALSA, and thereby remove PulseAudio; get everything standardized with ALSA like I had on Kubuntu, OR
2. How can I remove PulseAudio lag, and get the mic working with that, remove ALSA and get everything standardized with PulseAudio, OR
3. How can I simply make my mic work with the current setup?
Any of those will do. I just need to get my mic working.

At one point, I thought I needed pulseaudio for sound, so I messed around with installing it, even though at the time I had ALSA installed. (suffice to say, I know very little about linux sound). Pulseaudio never did work, I removed it with aptitude. But now ALSA seems to reach to pulseaudio for some reason.
Code:
More confusing is that there are no "alsa" looking processes in ps -A. But apparently, the basics are there
Code:
There's only one thing in init.d that seems relevent to alsa:
Code:
But doing this does not help anything. Does anyone know what to do from here?
And because I'm curious, how come I get sound from Flash Player and Audacity with no problem?

I just bought a powerful Sapphire nettop HD Mini-pc as shown here : [URL]
Installed a 32 bits version of ubuntu 10.10. Everything is working smoothly. So basically :
- installed 10.10 with usb key on HDD
- launch all update of the OS
- installed Nvidia closed driver
- update alsamixer to 1.0.23
So for now, I have in alsamixer 4 SPDIF out but no sound output from hdmi. HDMI output is well configured in the sound settings of ubuntu. I think this is linked to the ION 2 chipset and D510 proc.
dmesg|grep -i nvidia return :

I've recently encountered a sound issue and I recently installed the nvidia gt220 in my box and was thrilled at how well it worked with hdmi until I tried to use the audio. I updated my alsa and went into the alsamixer and it does detect my gt220. I unmuted all spdif and tested the sound and with success the sound test works. I know the card and device numbers that work with the audio but now sure where to make changes so it will default to that device instead of the onboard audio that it seems to try to use now. I am running lucid 10.04.
