Sound not working at all (OSS, ALSA)

[ChristofferS]

In Gnome sound is not working at all. When I try to use the audio device I get
the error message:

"ALSA device "default" is already in use by another program."

or "OSS device "default" is already in use by another program." depending on
sound card.

I found out that I had to do the following:

"ln -s /dev/audio1 /dev/dsp"

to get OSS sound working.

ALSA still does not work.

HI, have the same problem. Soundblaster Live.

"ln -s /dev/audio1 /dev/dsp" is not correct; those are two different types of
devices, and this will not work reliably.

Send the output from:

- dmesg
- aplay -l
- lsmod

I don't see any messages in your dmesg output which correspond to the sound
drivers loading. Are you sure it is complete?

Yes, it is complete. As a normal user I did this:

'dmesg > /tmp/dmesg'

and attached the dmesg file to bugzilla. I just tried again, and diffed the two
files:

You see, almost no difference (the RPC issue is something that I have fixed).

Lsmod shows that the sound modules are loaded. Should dmesg contain any info
about that ?

[Matt Zimmerman (mdz)]

Please send output from "cat /dev/sndstat"

It would appear that you have two sound devices. One is an onboard sound device
on your motherboard, and the other is a USB headset. By creating a symlink, it
would seem that you are redirecting audio output to the headset. Is that what
you want?

I don't know why you don't have /dev/dsp; that makes no sense to me. What does:

ls -l /dev/dsp* /dev/snd

show?

Everything seems to be detected correctly. You did not answer the question
about which audio device you wanted to be used, but it sounds like you wanted it
to use your USB headphones rather than the onboard audio, in which case this is
a duplicate of bug #8050.

This bug has been marked as a duplicate of bug 8050.

[ChristofferS (ubuntu-curo)]

Sorry about that.

I would actually like the onboard card to be the default, not the USB headset.

Does it change this bug's status ?
