slmodemd process hogging access to /dev/snd devices -> Sound Preferences -> Output tab -> "Dummy Output: Stereo" - Codec: Realtek ALC662 rev1 - Mixer: Nvidia MCP78 HDMI - ALC662 rev1 Analog [ALC662 rev1 Analog] Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio Controller (rev 03) - sound not working on System76 machine in Ubuntu 9.10 64-bit - using ALSA Driver version 1.0.21

Asked by Collin Stocks on 2009-10-26

I installed Ubuntu 9.10 a couple of days ago, and everything worked. Yesterday, the sound mysteriously stopped working after running flash (npviewer.bin) but came back again. Today, the sound is gone again, even after rebooting.

If I go into Sound Preferences and go to the Output tab, all it lists is "Dummy Output: Stereo". However, there clearly are devices:

where "00:1b.0 Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio Controller (rev 03)" is the relevant entry.

Furthermore, I installed gnome-alsamixer which detects the "Nvidia MCP78 HDMI" output device previously listed by "aplay -l". Any changes I make with it do not do anything for the sound. However, I am able to turn the volume up on the microphone, which is then played through to the speakers.

In addition, the Sound Preferences do not detect any input recording devices. However, "arecord -l" lists two:

###

I have made sure that I am in the groups audio, pulse, and pulse-access. I have rebooted several times and nothing has helped. I have checked the permissions on /dev/audio and /dev/dsp, and they both allow read/write access for the audio group.

Nothing in dmesg has anything to do with an audio device, so I won't bother pasting it here.

Anybody know how to help?

Collin Stocks (collinstocks) said : #4

I added the line:
###
load-module module-alsa-sink
###
to "/etc/pulse/default.pa" and now my sound and recording both work (though no sound recording devices are detected in the sound preferences ???)

I'd still like to know why this solution works, if anybody can elaborate.

Collin Stocks (collinstocks) said : #5

Thanks Mark Rijckenberg, that solved my question.

Collin Stocks (collinstocks) said : #6

I found a real solution to my problem, now. Apparently I was affected by this bug:
https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/394500?comments=all

My solution was to disable the modem driver, which I had enabled on some whim, and had forgotten about.

Now the sound totally works, and I don't need to use gnome-alsamixer in order to change the volume -- I can change it with the volume control in the notification area or with the volume shortcuts.

Collin Stocks (collinstocks) said : #7

By the way, I changed /etc/pulse/default.pa back to its original state. If you do not return it, you still will have no devices show up in the sound preferences.
