Re: [gentoo-user] Can't get ALSA OSS Emulation to work

[Nick Rout]

I can only suggest you look carefully at /dev/dsp - it should i think be
a link to /dev/sound/dsp.

Then look at the permissions on /dev/sound/dsp - they should be:

crw-rw----  1 root audio 14, 3 Jan  1  1970 /dev/sound/dsp

and the user trying to run the errant program should be in the audio
group. (and re-logged in if you add them as a result of this message, ie
adding a user to a group does not take effect until they log in again.
Unfortunately this can mean logging oput of X and back in again)

You can check if user is in the audio group with:

id user
