Ubuntu Multimedia :: Surround Sound No Longer Works Spdif Only Headphones Now
Jun 18, 2010
On my initial setup I follow the Comprehensive sound guide that is posted on the ubuntu forums because I wanted to get the spdif work Optical out with surround. After a while I was able some how to get it to work and but my headphones would no longer output sound so in an effort to get sound back to the headphones I maanged to ruin the the settings for the spdif.My question is how can I get spdif back and switch between headphones and spdif.I there no way to figure it out how do I purge every file that has to do with sound and recompile. ( THe comprehensive sound guide showed how to purge the alsa utils but that didnt work if someone know why please let me know and if you could explain.)

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 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 have Ubuntu 9.10. Clean install. I have a cheap headset but can't get sound to come thru the headset. The mic works, but sound only comes from main speakers.
I do not have a HP, SONY or anything like that. I bought my pc barebones and built myself. So there doesn't seem to be any easy fix for my pc. Here are the specs:

I am using Ubuntu 9.10. My sound works fine unless I have headphones plugged in. I've tried 2 sets of headphones, and it doesn't work with either set, so it's not the headphones. The volume is not muted (it's at 100%) for the headphones either in alsamixer. How can I diagnose and fix this?

I'm trying to get AC3/DTS passthrough working with my HTPC in which I'm using the onboard sound from an nForce 4-based motherboard. I've tested it in Win7 to check that all the connections etc are set up correctly and it works perfectly there. However under Kubuntu I can only get 2ch PCM sound to work through the SPDIF connection. Any DTS/DD sources just result in silence.If I go into Multimedia settings in the System Settings panel, the SPDIF device that shows up there (once I enable advanced devices) produces no sound with the Test button. I can hear a click as the device is activated but no sound is produced. I can also see that a digital signal is making it to my receiver as it has an icon which lights up when it locks onto a signal.Has anyone had success with SPDIF passthrough in 9.10? I've tried twiddling all the settings in Kmix relate to IEC and also tried following the Alsa wiki on digital passthrough without any success.

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.

I've just installed ubuntu on my new laptop, an Acer Aspire 5745G. I have a couple of problems. Of course I try to google my problems first, but these efforts were fruitless
Problem 1: Sound works perfectly on the laptop speakers, but when I plug in my headphones, I can't hear anything. The laptop speakers go silent, but there is no sound in the headphones. Very annoying.
Problem 2: I have wireless Internet connection, but the wired network connection doesn't seem to work. There is no activity when I connect the computer to the router.
Problem 3: The button for ejecting the CD-tray isn't the regular type I'm used to with laptops I've used before. On this laptop there is a button just above the numpad keyboard area, that's supposed to eject the cd-tray. This doesn't work, but I can eject it using a command in a terminal.

For months it was perfect. Simultaneous sound from both SPDIF and computer speakers. Today suddenly out of the blue no sound in SPDIF. If I click Test in KDE System Settings for SPDIF devivce that sound is played, so, I tried putting this device at the top, then sound comes only from SPDIF but not from the speakers!
God, why in Linux something perfect breaks into thousand pieces without any seemingly changes...

I just did an install on a new partition to upgrade my htpc. I'm unable to get any sound over SPDIF working. I do not have a receiver that accepts HDMI so I need to use spdif That said, i was able to test the hdmi portion of the sound with my tv and that appears to be working fine.[URL]Below is just the list of aplay -l

I just installed Ubuntu Lucid beta 2 on my desktop, and I can't seem to get the sound to work. I have a Soundblaster Audigy 2 card and the motherboard has built-in sound, but ubuntu doesn't recognize either of them. The only hardware option I have in my sound preferences is for SPDIF, and thats the only thing that shows up in alsamixer as well.

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.
; default-sample-format = s16le
; default-sample-rate = 44100
; default-sample-channels = 6
; default-channel-map = front-left,front-right
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.

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 just installed Lucid X64 on my PhenomX4 machine and I can't get my 5.1 speakers working. Only works in stereo.
Sound Preferences have only stereo options, how can I get surround 5.1? If it helps, I have Realtek for sound.

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 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.)

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].....

I got a 5.1 desktop sound sys for my recently built gaming rig. It sounds great. On Windows, that is. In ubuntu when I'm playing music, primarily when the subwoofer plays the bass, the speakers sound like they're farting and ripping phone books in half. Also, they get very statticy and sort of quiet. In sound preferences, analog stereo duplex is selected, if that's of any value. How can I get good sound playback in ubuntu?

I recently upgraded from 9.04 to 9.10 and the sound on my machine no longer works. I was previously using the OSS for sound. I'd like the sound solution that requires the minimal effort and I don't necessarily need to run OSS again. Ubuntu is installed on a Dell Optiplex 960.
Code:
aplay -l
results in:
Code:
aplay: device_list:223: no soundcards found...

I upgraded my system from 8.04 to 10.04.Now I keep getting errors saying that my adobe nonfree installation is bad. The worst part is that when I try to uninstall the Adobe package to start from scratch, it says that the problem is so bad that it can't be uninstalled, but must be re-installed.Of course when I try to re-install it, I get errors saying it's corrupt.I'm caught in a chicken and egg situation here.
Also, sound no longer works on my system.I think this is most likely a symptom of the first problem, but I'll just put it out there.I've read the other threads explaining how to fix this, but nothing works.

Well i will write this down one more time i hope you don't delete it again To enable surround sound with ALC888 on Intel DG31PR for all versions of ubuntu inluding Lucid.(this works on other distros with alsa as well) gksu gedit /etc/modprobe.d/alsa-base.conf Find this line (if there is no such line (or the file is empty) it doesn't matter just add the next line and save it)(note that on older Ubuntu versions the file is named "alsa-base" as far as i remember): # Prevent abnormal drivers from grabbing index 0
Add this line after the #Prevent abnormal drivers from grabbing index0: options snd_hda_intel model=3stack-6ch-dig Then use this command to edit pukeaudio: gksu gedit /etc/pulse/daemon.conf
Find this line:
; default-sample-channels = 2
Change it to (make sure to remove the ; in front of it):
default-sample-channels = 6

I found out there is no way to install headset's own drivers. At least I am looking for a way to switch its 5.1 property on. Is there any way for it on ubuntu 10.04 with pulse or whatever works?

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?
