Ubuntu Multimedia :: Sound Lost After Switching Output To Digital?
Jun 5, 2010
My sound was working, but I got a new SPDIF cable, so I switched it to digital. It worked fine. But then I restarted and now it's gone.
aplay -l tells me I have no soundcard but lspci -v lists
00:14.2 Audio device: ATI Technologies Inc SBx00 Azalia (Intel HDA)
Subsystem: ASUSTeK Computer Inc. Device 836c
Flags: bus master, slow devsel, latency 64, IRQ 16
Memory at f9ff4000 (64-bit, non-prefetchable) [size=16K]
Capabilities: <access denied>
Kernel driver in use: HDA Intel
Kernel modules: snd-hda-intel
So my soundcard is there.

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.

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:
Code:
Codec: Realtek ALC663
Codec: Nvidia MCP78 HDMI
aplay -l:

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'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.
Additional info:
- Ubuntu Karmic x64 (dist-upgraded from jaunty)
- Exaile media player with Normal playback engine and Automatic audio sink
- Asus P5Q-E motherboard
- Philips DFA888 amplifier

I'm using a terratec EWX 24 96 sound card with ubuntu studio, and I have sound with the digital output, I have no sound with the digital input.
I had sound with the same configuration in Windows XP, and all the hardware is ok.
I think I have no sound at all, with Ardour or Rosegarden, that's like if the digital input was not here in jack.

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.

I have a GA-MA785GMT-UD2H with ALC889A audio. I hooked up the optical cable and now only get sound from amarok. I don't get any sound from firefox or vlc. I looked at other posts but all refer to ubuntu and pulseaudio. I want to be able to use the optical out for all audio i.e firefox(flash) and vlc.

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].....

how to have alsa convert a digital sound stream to analogue before it is sent to the hdmi out? I would like to modify asound.conf. I do not have gnome as a desktop so I need to manually input the changes to asound.conf. The reason I ask is. I have sound going out of my acer revo to both spdif and hdmi. The spdif goes to my receiver and I want digital passthrough for that. The hdmi goes to my tv and I need it to be analouge before it gets to the tv. Right now, I get passthrough to both the spdif and hdmi. (the tv is all static) I want to have alsa convert the signal for the hdmi output only.

Alright, just installed maverick, got the sound to work great on the 7.1 with pulseaudio. works great in movies, and everything else just wonderfully. the only thing i am stumped by is how to get the sound to loop from my digital input on my soundcard to my analog speakers also on the same soundcard. i know the sound feed works on the input as the makeshift VU meter/bar on my digital input in the sound preferences moves, but i can't get the sound to actually come through on my speakers.

I have a fresh install of Natty and i'm having some issues getting sound to work. My laptop has a built in sound card which works just fine. However, i also have a usb 5.1 sound card which isn't working at all. Both devices show up in 'Sound Preferences' but when i select the 5.1 device as the output device sound doesnt work. I ran the alsa-info.sh script and the output can be found here.

My problem started when I updated Ubuntu 10.10 developer release (or whatever it's called ) to Ubuntu 10.10 Final. When I switch user or lock the screen and log back in, my computer makes no sound. I know it's not muted since I can see that in the volume control. The only way I can fix it is by restarting my computer

Maybe it's just an Amarok2 problem, but whenever another app (for example Konversation) plays a sound file, the audio instantly cuts out (in Amarok2) and will not come back unless I quit Amarok2 and restart it.
Amarok2 has only the options - "HDA ATI SB VT 1708S Analog" or "PulseAudio" (which is NOT installed).

Also I am totally confused by the mixer, it has so many knobs that I am totally lost!

I have made a pretty sizable mistake. I was trying to figure out why my game was having sound issues when I was told to update my sound drivers. After a bit of searching, I came across this website. I downloaded and ran the script in the first link. Minor problem: I was using PulseAudio, not ALSA. Needless to say, the script didn't work. After the machine rebooted, I had no sound at all. I was planning on switching to ALSA anyway, so I found this thread and ran the following commands:

I have had such good sucess with Ubuntu that this took me by surprise. Last week after an update I was suddenly without sound in Karmic Koala. Fortunately. I also have Lucid Lynx and the sound is OK there. I really gave it a dedicated try but was unable to get any sound.

Recently, I suddenly lost all sound coming in from firefox. Other sound works fine (e.g. Amarok), but I can't get any sound from type of source on the internet. There's also no sound coming from Opera.

The startup sound just desappeared. The Gnome Login Sound is still on the list of starting programs and the command is right (/usr/bin/canberra-gtk-play id=desktop-login description=GNOME Login). What makes it more weird is, that it works fine on all other users. I started to suffer from this problem since I tried to change the sound (I have done it before with no problems). At the same time with changing the startup sound I installed PulseAudio volume control. Could these things have something doing with my startup sound desappearence?

I think Virtualbox tried to do something to the kernal as I got an error refering to kernal version when I started Vbox.After that I had no sound.
I've tried to go through various sound fix threads but so far no success.
I've performed ALSA Upgrade:
Code:
paul@paul:~$ cat /proc/asound/version
Advanced Linux Sound Architecture Driver Version 1.0.23.
Compiled on Oct 6 2010 for kernel 2.6.32-25-generic (SMP).

I'm having a bit of a furball trying to change a soundcard. I took out an Audigy card. KDE detected the removal of the old card and asked me if I wanted to remove the drivers. I said yes. I went into the bios and enabled the onboard sound. Now I've got no sound so I guess I've got some configuration to do. So far:

I am not getting sound output from the system... i earlier got it...But after reinstalling I removed Sound applet from the Panel... Hardware is detected as it should be. I think it is because I configured the applet earlier, but as I removed it, I don't know how to restore it...
So tell me how to restore the sound applet as It is not coming in Add to panel menu....

I was trying to get help with video tearing but now I've lost all sound. This happened after using these two commands:
sudo mv /etc/X11/xorg.conf /etc/X11/xorg.conf.old
sudo dpkg-reconfigure -phigh xserver-xorg
I tried this:
ubuntu-bug audio
and got:
package audio does not exist
and:
ubuntu-bug -p alsa-base
and got:
Warning: The options -p/-P are deprecated, do not use them. See /usr/bin/ubuntu-bug
