[gentoo-user] Sound not working for user

[gentoo-user] Sound not working for user

[Grant]

Hello, sound related apps are no longer working for my user, but they
still do for root.  I get /dev/mixer errors for the user.  Is there
something simple I should check?  I do need to make a bunch of world
updates.

Hi,

check the permissions of /dev/mixer.

Hi,
make sure that the user is in the audio group.

Did you give a look at the approppiate gentoo-guide (probably
http://www.gentoo.org/doc/en/alsa-guide.xml , go to Audio Group)?

cheers

I did this:

gpasswd -a <username> audio

from the Gentoo ALSA guide but I get the same results.  I see
/dev/mixer and /dev/dsp errors.  What should their permissions be?

Actually it looks like rebooting after adding the user to the audio
group has fixed this.  Does that make sense?

relogin should have been enough ... ;)

Rebooting should not be necessary. Otherwise, yes it makes sense.

The id of a user are established when he or she logs in, so logging in
and out again is enough. To verify the groups you are in, try
executing "id" without options on the shell prompt.

After you add them to the audio group you have to login / logout. 
Permissions should be rw for the audio group

`find /dev -group audio -perm 660` should give you a good list of things 
that users in the audio group have access to

  It's actually PAM that's screwing things up.  There are two long-term
solutions...
  1) remove PAM altogether, which I eventually did, and am very happy
     with.  Note, you have to be careful.
  2) comment out all the entries in the specific PAM config file that
     sets permissions for devices.  My main machine totally died on me
     last night, so I have to check the Gentoo archive on the web.  I
     think the file you want to modify is /etc/security/console.perms
     by commenting out the line...
<console> 0660 <sound> 0660 root.audio

  Thanks to other problems, I eventually commented out the entire file.
A few more problems, and I dumped PAM entirely.  IMHO, PAM belongs in
the optional hardened security configs, along with NSA Selinux, etc.  If
you're an ISP offering shell access to several thousand customers, PAM
makes sense.  However, it is *NOT* necessary for the average desktop,
and only gets in the way.
