OpenSUSE Hardware :: Multiple Sound Apps In ALSA?
Feb 3, 2010
I have stated that I use Pulse because ALSA fails to utilize more then one sound app. With ALSA if I watch a ..... vid in firerfox and soon open my music player the music player wont work unless I close off firefox. so I close off firefox but sometimes flash hangs the sound device hostage and I have to log out or kill something to make sure ALSA is freed up. So this is why I use pulse, it makes using more then one sound app at a time much easier, no hang ups at all. But there are a few apps that dont get along with pulse so there must be a way to configure alsa to use more then one sound app at a time. Do I have some compiling to do? Is it commandline? I am just curious what you anti pulse folks do to use more then one sound app at a time without the aid of pulse. it only mumbles about the differences between the multiple sound servers.

So I've got a new system on which I had to re-install Debian, and I've been trying to fix the sound today, but it doesn't seem to work... I've kept the same ALSA configuration (except a minor adjustment to the card number as this system appears to have two cards instead of one), but it doesn't seem to work as expected. I got this weird error while running an app that uses ALSA:
Code: Select allALSA sound driver initializing...
ALSA lib pcm_dmix.c:1024:(snd_pcm_dmix_open) unable to open slave
--> (Device: default)...Failed: Operation not permitted
In VLC it works fine, provided that I manually choose the right device under Audio -> Audio Device.here's my /etc/asound.conf:
Code: Select alldefaults.ctl.card 1
pcm.dsp {
type plug
slave.pcm "dmix"

I'm having trouble getting ALSA to play multiple sound streams (multiple sounds at once). My code is running on an embedded ARM board using a AC97 sound. It will only play one without any mixing, I have to use pure ALSA as higher sound mixers are a nightmare to cross compile for ARM. I've tested my system with aplay for example
aplay -D plughw:0,1 bang.wav
works fine. So I tried dmix with
aplay -D plug:dmix Win.wav
That gave the following error
ALSA lib pcm_direct.c:1587snd_pcm_direct_parse_open_conf) The field ipc_gid must be a valid group (create group audio)
aplay: main:550: audio open error: Invalid argument
I checked asound with
/etc # cat asound.conf
pcm.EP93XX {
type hw
[code]....
Does this mean dmix will not work? Is there someway with the above setup I can play multiple sounds? I have to use the vendor ALSA build (so can't update ALSA), I can change the .confs however. Also because I'm cross compiling things like pulseaudio SDL are very difficult to get working, so I basically need to use the above ALSA. Is there anyway I can find if dmix exists on the system?
Should add aplay -L does show dmix ?
iec958 'cards.pcm.iec958'
spdif 'cards.pcm.iec958'

For some reason my sound stops working in KDE4. I can't trace it to any particular event, it seems to happen randomly. I think the problem started when I tried installing ktts (the text to speech engine) but I cannot be sure. I've now removed ktts but my problem persists.The strange thing is that if I go to the sound configuration in yast and play the test sound it works fine. But if I try play the test sound in multimedia settings from within systemsettings then I get an error saying "The audio playback device HDA Intel (AD198x Analog) does not work." Also that error message window is titled phonon.
I didn't install phonon but notice that it's installed. I assume it was installed with the default install because trying to remove it brings up over a 100 dependencies.The left speaker / right speak test from the konsole works but only as su and not as me. I get permission errors. Is that normal?
Code:
speaker-test -c2 -l5 -twav
speaker-test 1.0.21
Playback device is default
Stream parameters are 48000Hz, S16_LE, 2 channels
[code]....
I also notice that sometimes when I boot up, after I login at the graphic login screen it kicks me out to the command prompt asking me to log in again. When I log in and "startx" KDE starts up but without sound and no kmix. Trying to start kmix manually doesn't start it. I just get an empty window.Again the sound works from the yast sound test.I've tried removing the kmix config files from /.kde4/config/ but that doesn't help. The logs don't show anything obvious to me and the problem appears to occur randomly in so much I haven't been able to figure out what triggers it yet.I also noticed during a session that I have this sound problem and after I've fixed it by resetting the sound card in yast that kde doesn't shutdown when trying to shut the laptop down.
I get the kde logging off chime but the desktop remains and is fully functional. After that any attempt to log-off or shutdowm is ignored. I'm forced to run the shutdown command from the konsole to shut the laptop down. I'm not sure how it's related but it only happens after the sound problem occurs. I'm using KDE4.4.1 but this started in KDE4.4.0 so the update didn't help any. When I upgraded to KDE4.4.0 I started with a fresh .kde4 directory.

1. I run Suse 11.2 with two sound cards , one HDA comes with motherboard and second is USB, which I use for skype and talking. In YAST everything is fine the motherboard card is marked as prime card and the usb card is marked as second. But often when I log in alsa decides that second card is main and I have to pull out the USB card, run command "rcalsasound restart" and put the USB back afterward. It is a way that to be fixed in the way that alsa remember my choices forever. 2. The other problem is that from time to time the sound suddenly dies and I have to bring it up with rcalsasound restart again.
But I have to admit that their significant improvement with managing sound with PulseAudio.

I've got sound - I hear all the system sounds, I can play sound files, CDs, etc. But I have not been able to record and play back anything with success.
Originally, when I would record (either with arecord or with audacity) I would get extremely low quality sound, with lots of noise and crackling, and my recorded voice was barely audible (even with volume turned up to max). I played with alsamixer for hours without being able to improve matters.
Things are worse now. I tried installing alsa-firmware, as indicated at SDB:Audio troubleshooting - openSUSE. I also tried updating alsa following instructions given at SDB:Alsa-update - openSUSE. I'm not sure which of these changes did it, but the result is that I can no longer record ANYTHING at all. I get absolutely nothing, not even the low quality noise and crackling I was getting before. It's as if there is no audio input at all.
Uninstalling alsa-firmware and reverting back to the older alsa version (1.0.20) didn't change a thing.
I'm running openSUSE 11.2, kernel 2.6.31.14-0.6-desktop, alsa 1.0.20. My sound card is a Creative X-Fi (by the way, yast cannot detect my card, another problem I have never solved).

I have just installed OS 11.3 onto a lenovo desktop / Thinkcentre that previously had vista installed on it. With Opensuse I am having trouble getting much sound volume. With Vista the volume was fine but with Opensuse I have PCM, Master running pretty much on full. This gives me a respectable volume but I think there should really be more left in the tank from what I have it at. Is there any way to increase the gain in Alsa? The sound device shows in KDE as HDA Intel (AD198x) using xine backend.

When I go to Computer, Control Panel, Sound and look at the Hardware tab, nothing is there. In the Output tab, 'Dummy Output' is the only item listed. In Sound in Yast2, the device shows correctly as Card Model - Thinkpad X61, driver snd-hda-intel.I click on "Play Test Sound" through there, it works fine. Mplayer (from a terminal session), Gnome Mplayer, Banshee, and Totem all don't play sound

I have recently been forced to do a hardware upgrade (my previous mobo died). Now, sounds works ok with,amarok because kde has recognized the new hardware and switched to it.
..... does not work, likely because flash uses alsa-oss which is probably not configured automatically. I have tried uninstalling and reinstalling both alsa-oss and flash, but it didn't solve the problem.

I have installed xubuntu version 10. My sound card is a Yamaha dS-1S, and seems to be properly configured. Alsa mixer doesn't indicates any error. However, I can't manage to get any sound. I have checked that jacks are correctly plugged.

I'm running Kubuntu 9.10 X64, and am using ALSA for my sound. I have no trouble with sound: VLC, Adobe's Flash plugin, Java, etc. all work properly. When I run the Gnash standalone player, sound does not work at all.
When I run Gnash in a terminal, I get this:

I've switched off the borg at home 100% (yippee). Wife and kids are now logging on, firing up 2-3 apps (usually FF, songbird and nautilus) and then switching users to allow the other on. This has the unexpected side effect of locking the audio device so the other user cannot use it until they shutdown those apps that have /dev/dsp open in a locked fashion.Is this "normal" behaviour? or is there something I'm missing in the setup?

I've worked out how to get ALSA libasound code working for an application. However I can't workout how to get multiple sounds working at once. I can't seem to find any google examples of mutiple sounds. EG tune plays while pressing buttons makes clicks. I'm using an embedded board so need to use ALSA not an addon e.g. sdlmixer, jack, etc.

I have an Intel HDA audio card, and would like to record both my soundcard output and my microphone input at the same time. Getting to record my soundcard output (aka "Stereo Mix" or "What-U-Hear") is impossible for my soundcard without using the PulseAudio monitor, so I've set that up. Now I can record either the PulseAudio monitor for my soundcard, or the microphone input, but I don't know how to record both at the same time.
Currently, my .asoundrc looks like this:
Code:
pcm.pulse {
type pulse
}
ctl.pulse {
[code]....
So now I can choose either "pulse" as an input channel in, for example, Audacity or RecordMyDesktop applications (and then set in the PA volume control the actual channel which I want recorded), or choose "pulse_monitor" or "pulse_mic", in order to record either the PA monitor or the microphone, respectively.
I've read through the ALSA plugins reference, as well as the Asym and Dmix pages on ALSA wiki, but I'm still not sure how to put this together. I figured there should be a way either to route the microphone input into the ALSA output, and thus make the PA monitor "hear" what I speak into the microphone, or to make a completely new channel with both ALSA output and microphone input as "slaves", and then use that for recording.

When I had UBUNTU 10.04 sound WORKED!I have post several threads about this issue, I hope this would be the last one, My OS version is Ubuntu 11.04, my hardware is: Nvidia GTS 450 video Card EGS; and an integrated sound card reference: Via Azalia HDAC VT1708/A; After installing ubuntu I had no audio through my integrated sound card, I cant use my NVidia HDA card because I need for it an HDMI AUDIO, and I dont have any HDMI sound devices like dvd or TV. So I need to use my integrated default Via soundcard. I Updated the OS, nothing changed. After typing aplay -l it showed this:

basically, sound will cut in and out. if i'm on videos, whenever sound cuts out, the video will continue for exactly two seconds and stop. sometimes i can reload the videos video, and it'll either play for two seconds without sound, or go normal, but usually for only a little time, not even a minute. similar problems for amarok, spotify and other applications using the sound card. this is the output when trying to restart the alsa demon
code:
root@muspellsheim:/etc/rc.d# /etc/rc.d/rc.alsa restart
loading alsa mixer settings: /usr/sbin/alsactl restore
unknown hardware: "ich4" "realtek alc650f" "ac97a:414c4723" "0x1462" "0x5770"

some of the utput of lspci -v
i've tried reconfiguring alsa by using the alsaconf application, which didn't help. the output from restarting the alsa demon, may indicate that the correct driver isn't loaded.

Using more than one instance of the same app is a real pita in Unity.If I have 3 (or more) pdf documents open in evince then there isn't a way to shift from one to the other using the mouse. Previously I had the windows on the taskbar and could click on the one I wanted. In Unity clicking on the evince icon on the launcher just brings ALL the instances of evince to the top - I still then have to shuffle the windows around to get the one I want.I've been trying to get used to Unity over the last few days, so maybe I am just doing it wrong, but if not then maybe I should file a bug report?

I am having problems getting sound to work. I have pasted my output from AlsaInfo.sh in hopes that someone can assist me. I have been able to fix this with the AlsaCompile scripts for Ubuntu. I am wondering if this is a distro related issue. If not I will gladly send to the alsa project.

I am using linux mint 9 with kernel 2.6.32.29. I upgraded from alsa 1.0.23 to 1.0.24 using the alsa upgrade script. Sound was working just fine before on my Asus Xonar DS, However, my nvidia geforce 430's hdmi audio card is not recognized in 1.0.23 but it is in 1.0.24. Though the card is detected, I have no sound on either cards now.

when i plug in my headphones i was getting sound output both from the laptop speakers and the headphones, then i tried changing the sound.conf file and still no success and then i tried reinstalling the alsa - i downloaded the latest alsa-driver and alsa-lib and installed them, but when i rebooted there was no more sound from the headphones when i plug them in. I don't know what to do, i tried reinstalling alsa multiple times but still no success. Is there any way to bring back my previous configuration when i installed slackware ? Or some way to roll back using the installation dvd ?

I'm trying to create a bash script that will open firefox, evolution, gedit (specific file), etc. For the most part it works, but after it opens evolution or gedit, it pauses execution, until I close that app down.
I don't want to have this done at login, i want to pick and choose when I open them all.

I am running XBMC-standalone on a minimal Ubuntu installation and everything works as it should almost out of the box ... Now I would like to use my remote to navigate through ultrastardx which I start as an app(within XBMC).
I use linux-input-layer(devinput) with lirc(=necessary to make all buttons work).
So, if I start ultrastardx with the configuration from above my RC does not work at all but when I kill lircd before I start ultrastardx I ll get basic functions like Left, Right, Enter,... This is great but I miss two main functions Jumpto and search. To get them work and tremendously increasing the WAF I would need to send a key-sequence to ultrastardx.
What do I have to do to send such a sequence like "alt+j"?
Is there a way to kill lircd automatically before I start ultrastardy(at the moment I have to this manually )?

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?

Initially the sound was working fine in my ubuntu 10.04 lucid. Headphone jack was not working. I downloaded and installed following packages in order to upgrade alsa.
alsa-driver-1.0.15rc3.tar.bz2
alsa-firmware-1.0.15rc1.tar.bz2
alsa-lib-1.0.15rc3.tar.bz2
alsa-utils-1.0.15rc1.tar.bz2
Now there is no sound. Whole system is fried. I don't know what happened.

I recently converted an amd 64 bit WINdows machine to Lucid 64 bit. Everything has gone well. I had numerous issues with Pulseaudio that I removed it. Sound with Alsa has been great, including system theme sounds. I can record via a mike as well. What I cannot do is to capture sounds coming through the sound card. When I record I am getting empty files. The mixer indicates that there are two capture devices. Here is some data on my audio card.
