Debian Squeeze: No Sound

[colorfull]

I believe the problem is with pulseaudio and not alsa. I noticed that the sound was totally muted each time I logged in to Gnome. I googled around a bit for an answer and found something that works for me. In the file /etc/pulse/default.pa I commented out the line "load-module module-console-kit", rebooted and the system sounds started playing.

It works for me but uncomment the line "load-module module-alsa-sink"

Had the same problem, not sure if this is covered in the previous 5 pages, but:

run alsamixer
then type 'm' to unmute (which is signified by the 2 m's below each volume control.

I had the same problem...

I found if I reset alsa then my usb headphones would work. So I created a script to load each time on startup.

This is what I did exactly.

and now I have sound working. I know this isnt the fix. But a great work around.

[RTFM]

Hi,

I have a fresh new Squeeze installation (Debian 6.0.4) with all available updates installed.

Before that I used Debian Lenny. In Debian Lenny I could hear sound well.

In Debian Squeeze sound output is very very quiet. I can hear sound if I put the volume of my stereo amplifier to a very high volume, but sound is very very quiet.

I did not change the sound hardware in my computer when I installed Debian Squeeze.

The following sound devices are part of my machine:

- a HDA Intel onboard sound device
- a Soundblaster Live 5.1 sound device

Debian Lenny was configured to only use the Soundblaster card for sound generation, and it worked well.

In my Debian Squeeze installation I was first confronted with the fact that /proc/asound/cards listed both sound devices, and the HDA Intel onboard sound device was the default device.

Note that I want to use the Soundblaster 5.1 Live card for sound generation, not the HDA intel onboard sound device.

So first I ensured that the HDA Intel sound device is not listed anymore in the /proc/asound/cards file. I achieved this by blacklisting the drivers for the HDA Intel sound device, i.e. I put the following lines into /etc/modprobe.d/alsa-base-blacklist.conf:

Code: Select all

blacklist snd_hda_intel
blacklist snd_hda_snd
blacklist snd_hda_codec

After that, after a reboot, the command

Code: Select all

cat /proc/asound/cards

showed and still shows:

Code: Select all

0 [Live           ]: EMU10K1 - SB Live! 5.1
                      SB Live! 5.1 (rev.7, serial:0x80641102) at 0xcf00, irq 20

So this is what I wanted: The HDA Intel sound device is not detected anymore.

The command

Code: Select all

lsmod | grep snd

gives now:

Seems fine to me.

The command

Code: Select all

aplay -l

gives

In my normal user account I used the command

Code: Select all

alsamixer

to set the volumes right for Master, PCM and Wave. I put these channels to the value "80". I ensured that these channels are not muted.

Amarok is not installed.

I uninstalled the following packages:

Code: Select all

pulseaudio gnome-audio gstreamer0.10-pulseaudio libasound2-plugins libpulse-browse0 pulseaudio-util

Note that my desktop environment is KDE, not GNOME.

My normal user account is part of the audio group:

Code: Select all

id <my normal user account>
uid=1001(<my normal user account>) gid=1001(<my normal user account>) Gruppen=1001(<my normal user account>),29(audio)

When I start the test sound button in KDE system settings > Multimedia, then sound output is very very quiet.

In a shell belonging to my normal user account a mp3 file can successully be played with mpg123 and mplayer, but the sound is still very very quiet.

mpg123 does not show any errors while the mp3 file is played.

mplayer gives the following error messages while the mp3 file is played:

Code: Select all

Can't open joystick device /dev/input/js0: No such file or directory
Can't init input joystick
mplayer: could not connect to socket
mplayer: No such file or directory
Failed to open LIRC support. You will not be able to use your remote control.

I do not have any remote control, so this is okay.
But to what do the lines

Code: Select all

mplayer: could not connect to socket
mplayer: No such file or directory

refer? Might this be a hint about that something is wrong with my sound configuration? Or do they refer to the missing joystick (seems so)?

But my general question is: How do I get a reasonable volume? Currently sound is very very quiet.
Note that during all the configuration changes that I applied, there was either no sound output at all, or it was (and is) very very quiet.
During all my configuration changes I never could hear a reasonable volume.

Problem solved: I took a nap, When I woke up I remembered that I had cleaned that external audio mixer device from dust before I installed Debian Squeeze. And I thought that I might had changed some settings of that external audio mixer device. And yes, I was right: I changed the input channel at that external mixer device, and voila: now I can hear sound well while Squeeze is running

Had the same problem, not sure if this is covered in the previous 5 pages, but:

run alsamixer
then type 'm' to unmute (which is signified by the 2 m's below each volume control.

Perfect thank you.

Now, I just need to convince every single Icon and the Minimize/Maximise/Close boxes to reappear/work

[dupko]

I just lost my sound again while using Rhythmbox. Any clear solution???

PLS. HELP!!!!!!!

i have the same problem

[tstanton]

Had the same problem, not sure if this is covered in the previous 5 pages, but:

I had a channel in alsamixer labeled "Beep." It was muted. Unmuting it seems to have fixed my sound as well. Thanks!

[diegoiee]

All you need to do is : apt-get purge alsa*

[sbrothy]

I also have no sound. I using a fresh squeeze install:

Code: Select all

# alsactl init

# aplay piano2.wav

Following some of the instructions here I did

Code: Select all

# lspci | grep -i audio

... so I tried to create the suggested /etc/asound.conf as:

Code: Select all

pcm.!default front:SB

I also tried "Generic" but that didn't work. Rebooted and now

Code: Select all

# aplay piano2.wav
Playing WAVE 'piano2.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Stereo

Also where the test option in gstreamer-properties gave an error message before it now actually looks like it's playing but still no sound!.

I'm going nuts! Can someone shed some light on this?

[sbrothy]

Never mind. My problem was solved by putting

Code: Select all

options snd-hda-intel model=MyModel

into /etc/modprobe.d/sound.conf as described here:

https://help.ubuntu.com/community/HdaIntelSoundHowto

For my own future reference it's

options snd-hda-intel model=hp

and also put:

pcm.!default {
type hw
card 1
}
ctl.!default {
type hw
card 1
}

in /etc/asound.conf

Reboot. Et voila.

I went through all the thread with no luck. At the end, I solved by opening the "Volume Control: Intel 82801DB-ICH4 (Alsa mixer)", moving to the "Switches" tab and deselecting the "Jack Detect" field!

Hope it could solve for someone else too.
