[Solved] Sound card not recognized by pulseaudio

Postby gitterrost4 » 2010-01-18 09:56

Hello,

under Debian Testing, pulseaudio doesn't detect my sound card. In the "Sound Preferences" Dialog I only get "Dummy Output"

lspci:
Code: Select all
    $ lspci | grep -i audio
    00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio Controller (rev 04)

Does anyone have an idea?

Might try:
Code: Select all
Change /etc/modprobe.d/alsa-base.conf

# Power down HDA controllers after 10 idle seconds
options snd-hda-intel model=dell-3stack

sudo alsa force-reload

In 'Sound Preferences' -> 'Hardware' set Profile -> Analog Stereo Duplex


Pulseaudio is one of those things that if you can do without it you are better off not using it. It is buggier than windowsme.

I did this, and after the alsa force-reload command my sound worked.

Now I have to use the reload command every time I reboot my system.

Furthermore I would prefer to continue using PulseAudio

A friend (now a very good friend) of mine helped me out. Apparently the application speech-dispatcher was installed and somehow blocked the sound system. After removing speech-dispatcher everything worked fine.

For the record: This showed the problem
Code: Select all
$ sudo lsof /dev/snd/*
COMMAND    PID              USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
sd_espeak 1978 speech-dispatcher  mem    CHR 116,16          3288 /dev/snd/pcmC0D0p
