OpenSUSE Multimedia :: 11.4 - Lost Digital Surround Output
Mar 10, 2011
Alright so I just upgraded my 11.3 x64 to 11.4 using zypper dup and have now lost the ability to play digital output 5.1. Before doing the upgrade I was running alsa rather than phonon but apparently the upgrade decided to enable phonon, and I no longer show digital surround output. The soundcard I have is a CM8738 and I am using the coaxial output on it hooked into my receiver. In system settings->multimedia->phonon->speaker setup the soundcard shows and I have the ability to select different profiles.
However the digital output settings only show stereo and the sound output device the only one listed is CM8738 Digital Stereo (IEC958). I have selections for analog 5.1 and analog 7.1 but neither put anything out of the digital connection. As I said I was running alsa before and was able to do straight digital pass through which allowed my receiver to do the decoding and use all of my channels. How can I setup phonon to use digital passthrough, or switch back to alsa and get that setup again.
Here is the update to the old thread that somehow disappeared "HOWTO: A52 Encoded 5.1 Surround Sound Awesomeness with PulseAudio and ALSA on Hardy" thread (archived here). See also this bug report.There are two steps here: add the a52 plugin, and tell pulseaudio to use it.
Step 1: Go to a terminal and do the following:
Code: sudo bash echo "pcm.a52 {[code]....
Pulse should come back on its own unless you disabled autospawn.Now pulse should be aware of your digital surround output. Go to System -> Preferences -> Sound. Click on the "Hardware" tab and change the profile to one of the 'Digital Surround 5.1' profiles. Play some sound (I like to test with www.pandora.com) and enjoy!If it doesn't show up, it probably means that alsa didn't create it correctly. To test if alsa sees the a52 device, type:
Code: aplay -D a52:0
If it errors out (audio open error: No such file or directory) then that means it did not like your asound.conf settings. You might learn something by looking at the output of 'sudo alsa reload' or just 'aplay'.[code].....
Currently using an Asrock ION 330 with an SPDIF output and running 10.04It works as stereo but can't get the system to run as surround sound and everything shows as 2 channels only.The hardware itself supports it fine as it works under windows 7 without issues so it has to be a config issue somewhere.I have tried everything I can find via google including upgrading the alsa drivers but so far there has been no change.
I would really like to get digital (5.1) surround in Ubuntu 10.04 with pulseaudio. However, when I go to the preferences->sound->hardware setting, I can only select analog surround outputs. The only digital outputs shown are stereo.
I've done a search on google and on here regarding my issue and I couldn't see anything.
I have the following audio device;
Code: 00:10.1 Audio device: nVidia Corporation MCP51 High Definition Audio (rev a2) At the moment I have it playing through Analog Stereo Output. (See attached image)
The sound is mostly flawless and I haven't been having troubles with it.
But, because I play audio through my logitech speakers (2 speakers, 1 subwoofer) I should be able to get digital stereo sound shouldn't I?
From the drop down box of the attached image there are two options for Digital Stereo;
Digital Stereo Duplex IEC958 Digital Stereo IEC958 Output + Analog Stereo Input
None of them work for me. Even if I do a restart, I get no sound from Rhythmbox or Firefox.
I use the pulseaudio sound server and I have the PulseAudio device chooser installed. When I had the Digital Stereo Duplex IEC958 selected I used the Volume Meter playback to see if there was any sound coming through. Both left and right showed activity but nothing came through the speakers.
After some fudging around, I managed to get my 64-bit karmic install to output sound digitally to my amplifier. So far, so good. The amplifier indicates a sample rate of 44.1KHz, while it is capable of 48KHz (higher sample rate would be better, i assume). Also, more annoying, it indicates no signal when no applications are producing sounds, causing it to miss the first second of output when I unpause my music. Windows 7 outputs everything as 48KHz, apparently also outputting silence as the light doesn't blink when i pause a media player.
The question then being: How do I override the default sample rate of digital audio output (if this is even possible, googling suggested that this might be overridden by applications); How do I make my sound driver output silence when no application is outputting sound.

I am attempting to configure my HTPC with FC13. You can see my hardware configuration at the following link.The problem I am facing is trying to output surround audio using the spdif (optical) interface. The system correctly recognizes the integrated sound card (MCP78S High Definition Audio), but fails to offer the option of digital surround output. The only option for digital output is plain stereo. On the other hand it does offer all the analog surround output options.I have tried modifying the /etc/pulse/daemon.conf and specifying it to use 6 channels, but it still uses just 2. And for added grief, it sends one of the channels to the subwoffer instead of the front right channel.
My 785G motherboard comes with an integrated sound card. In the manual I see there is an option to install Dolby Software to make 2-channel stereo sources play to 4, 5.1, and 7.1. Is there any equivalent Dolby or other software for OpenSuse 11.2?
I have just upgraded my box to be more multimedia friendly and one of the upgrades was to improve the sound card. I decided to get the Asus Xonar DX pci-e card. I have it working but the speakers are not plugged into the front output socket as the xonar dx only plays sound from side surround output. Will the sound be any better from the front out on my 2.0 speaker system or is the sound being directed out of the side surround out full quality? How to overcome this discrepancy?
I have a brand new Sony DPF-D75 Digital photo frame. I tried connecting it through the usb port with my 11.3 box in order to upload my pictures to it, but it isn't automatically mounted (unlike any other usb device I plug in, like my mouse & pen drive). Should I install any specific driver or something?
Sound comes out of my laptop speakers, but only when hardware is selected as "Analog Stereo". "Digital Stereo" does not function at all. I don't think this is a priority though.
More importantly, my headphones do not have sound unless it is only partway plugged into the headphone jack. However, this does not help as sound is still coming out of my speakers. The instant I plug it all the way in, the sound disappears from both speakers and headphones. I have not tested this with multiple headphones (no access), but these ones work just fine in Windows 7 plugged in all the way.
I have tried an amazing number of things back in '09 when I was running 9.10, but gave up as no one could provide the answer. The threads that are related are: [URL] (Don't worry about read-only file stuff, that is all resolved) [URL]
I am now on a FRESH install of 10.04 Lucid Lynx, so any changes I made in attempt to fix it is gone.
Looking into alsamixer, I found that there is a headphones column, but no bar. It just says it's on. So headphones don't seem to have their own level of volume that's set too low.
Here are some outputs: lcat /proc/asound/card0/codec#* | grep Codec:
I am running openSUSE 11.1 with modified Kernel. While trying to run make on the downloaded driver for the RTL2831 I am getting an error message that I do not full understand. That is:
Code:
linux-2c5j:~/rtl2831-r2 # make make -C /root/rtl2831-r2/v4l make[1]: Entering directory `/root/rtl2831-r2/v4l' No version yet, using 3.0.4-41-desktop
[code]...
I am not sure what is required when the error is "first use this function". How can I use the function T_DIGITAL_TV if I first have to install my driver in order to use the stick?
Ubuntu seems to see my onboard audio card but I can't select it in the Sound options as my output. In Alsamixer I can adjust settings and have turned on SPIDIF. It's listed when I run the lspci command as
Code: 00:1b.0 Audio device: Intel Corporation 82801JI (ICH10 Family) HD Audio Controller So what is the problem?
I have Gateway P-7807u laptop with Ubuntu 9.10 installed, it has HDMI output and I use it to connect to my TV-set. The problem is - not working sound via HDMI, in sound preferences I've chosen duplex digital output, but no success, but picture works well.
I have a shared headphone/spdif jack on my ASUS B53J and am running Ubuntu 11.04 Natty. I am not able to get the digital spdif output to work. I have tested the spdif out under Windows 7 and it works perfectly.

After many fruitless weeks of reading forums, newsgroups etc, I still fial to get digital output working my SoundBlaster Live Platinum. Ordinary PCM output is passed to the digital receiver witout a problem, but as soon as I try AC3 or DTS it's all silence. I have unmuted the IEC958 channel in alsamixer and added gain to them. However all still fails. find below the output of relevant commands:
uname -a Code: Linux Mediacenter 2.6.31-14-generic #48-Ubuntu SMP Fri Oct 16 14:04:26 UTC 2009 i686 GNU/Linux aplay -L Code: default:CARD=Live
I've setup an HTPC with xbmc, and I'd like to output the audio from the system to both my digital and analog outputs on my mother board. How do I do it? Can their be a script that duplicates the output of one to the other? Here's what aplay -l said:
Alsa says I'm using a HDA ATI SB audio card with realtek ALC662 rev 1. chip, I've set the default channels to 6 for 5.1 in /etc/pulse/daemon.conf but got only stereo.
I would assume I have to do something with the channel map, but I don't know where to begin. I can say it is not a hardware issue as it works fine in windows 7 where my mic in is my sub-woofer/center out and my line in is my line in is my rear speaker out. I tried going into sound preferences to see if I could get it to use line in and mic in as sub-woof out and rear out , but there was no such option. All I was allowed was analog duplex 1 output / 1 input.
I'm having trouble after installing Lubuntu-desktop on top of a Ubuntu Server (64 bit). about the reason for this abomination of distributions is to achieve 64 bit Lubuntu. I used to run Ubuntu 64 straight, but didn't like Unity at all; Arch Linux was great up until now, but I'd like to settle down and focus more on productivity.
The situation is thus: I cannot manage to make my X-Fi USB sound card work without hacks, and at best it only works in some applications. I *think* it may be a bug in ALSA, but I had no problem in the latest versions of Ubuntu (11.04 as of this) and Xubuntu even (11.04?).
I can currently only play media in VLC media player using the following hack in my ~./asoundrc
Code:
This works as expected, but not for many applications (which fail to launch, with a error message related to below (no mixer controls))
Code:
What could I be missing? Some diagnostic information (any other information on request):
When I decode an audio clip which contain 5.1 streams (the encoding doesn't matter - or does it?) I cannot find an option which allows redirection of the lower frequencies (from front, back and center channels) to the sub woofer (LFE channel). I understand that this perfectly normal and this is how 5.1 supposed to work. My problem is that my speakers are not full range, so they cannot reproduce the bass in the streams. What I want to know is if there is a way to do something like this: [URL]
Which is described as: Bass redir - Bass redirection. Route basses from all channels to subwoofer. Works only if it is subwoofer at output speakers. Highly recommended for systems with separate subwoofer. Basses are routed before mixing so basses are shown at LFE input level (although 'real' LFE may be absent).
I'm aware of the enable-lfe-remixing = yes option. It works fine for stereo, but not for 5.1
I use ubuntu 9.10 and my pulseaudio version is 0.9.19. The player I use most is SMPlayer (version 0.6.8 (SVN r3213)) and AC3-liba52 for AC3 decoding. My system is up to date.
I own an external usb soundcard: Creative Blaster X-Fi Surround 5.1. After some tweaking around Multimedia Settings, (K)Ubuntu 9.10 successfully detected the card. I can now use it.
However, setting the sound level in KMixer does not work at all - KMixer now only contains a Microphone channel. Using hotkeys, I can still turn volume from 0 to 100%, but that has no effect on the volume produced by the soundcard. The sound card comes with a sound joggle, but turning it left or right has no effect whatsoever on the volume level.
Is there a way to solve either of these issues? p.s. Also, the card came with a Windows app and driver cd.
I've been trying to get my surround sound(5.1) to work for the past couple of of days, followed a number of guides, but nothing seems to get it working at all. I'm connecting the speakers using 3 analogue audio cables, I have tested and they work fine under Windows. When I go into the Sound options in Ubuntu I don't see a 5.1 profile listed under the Hardware tab, only stereo(and that works fine).
The sound controller is a Realtek ALC892 built-in to my mobo(Gigabyte P55A-UD3).
Here is some info I've seen requested in other threads, I'm running 10.10 RC, but I can assure you it doesn't work under earlier versions.

I just got a 5.1 Surround sound system and set it up. I found that it was only working as stereo, though (That is, only the two frontal speakers were producing any sound). I made sure everything was not muted in alsamixer and checked that the hardware was set to 5.1 in the Sound Preferences Hardware tab.
I'm using Ubuntu 10.10 64bit and my sound card is an onboard Intel DG41TY, Realtek ALC888VC codec.
I recently purchased a Creative Fatal1ty headset with a USB connection, and was wondering if it's possible to use its 5.1 surround sound capabilities under Ubuntu.
I have a Acer Aspire Revo R3600 running Ubuntu 10.10. Its a clean install, all I have done is update the NVidia drivers and ASLA. The PC connects to my AV Receiver via HDMI and I have stereo sound but no surround sound. If I go to System > Preferences > Sound and look under the hardware tab I only have "Internal Audio Digital Stereo (HDMI) Output" and no mention of surround sound or 5.1 etc. I assume this is part of the problem.
I have these Creative Inspire M4500 4.1 surround sound speakers.I got them to work succesfully on my older computer by installing the ALSAmixer. and then unmuting the channels. However on my new computer even after installing ALSAmixer, i cannot seem to be able to get playback from my rear two speakers. I tried the community ubuntu documentation and ALSA's own guide(which seemed too complicated for me.)
In my dell xps 15 i have an onboard sound card which is 'Intel High Definition audio' code...
the problem is my sound system (Creative INSPIRE 5300) take input through three 3.5 mm jacks one for front right and left, one for rear right and left, and one for center and subwoofer. In windows 7 when i connect each jack it asks me which device am i connecting and i can select each one accordingly. (the rear two speakers were connected to the mic in port of the system.) now in ubuntu 11.04 i cannot configure the system to get the sound out through the 3.5 mm jacks.. i can select the sound device to get the sound out through the hdmi port but unfortunately i don't have an hdmi surround system.
