xmms & alsa permission problems

kadaver · 12-13-2003, 07:20 AM

First of all, i spent the last 15 minutes probing the forum for this, didn't find it so don't be like "ARGH ARGH USE THE SEARCH FUNCTION MTFU!!!" =)

ALSA is now up and running and it works sooo much better than OSS did.
Two problems though:

1) Whenever i start xmms (root or nonroot doesn't matter) i get an error message saying:

"libartsc.so.0: failed to open shared objects file: the file or folder doesn't exist."

But as root xmms still runs and the sound works anyway, but it's annoying..

2) When i start xmms as a normal user i get the following errors (except for the libartsc.so.0 stuff):

"**WARNING**: alsa_setup_mixer(): Attaching to mixer hw:0 failed: Permission Denied"

Obviously it's a permissions issue, so I went and did this:

"chmod u+rw /dev/dsp* /dev/mixer* /dev/sequencer* /dev/midi*"

Still doesn't work.
In other words, sound works as root but not as a regular user. What to do??

Thank you for reading...

I was able to get is going by
adding

# chmod 777 /dev/amixer*
# chmod 777 /dev/snd/*

This appears to be the alsa mixer
and I also added the user to the "sys" group

I hope that this helps

Oh and this is totally not secure

I know =)
Got it working now, I reset all the permissions to default and added myself to the sudoers file instead. Much more secure, and a much more correct approach =)

SOMEtimes devfsd doesn't initialize correctly/ontime and the /dev/snd/* doesn't get it's permissions set correctly.
I have noticed that just today. At first I didn't know what the reason was. xmms just complained and a reboot fixed it.
Call me lazy, but it didn't bother me.

Today I got it again, 4th time now and it was starting to get annoying. So i launched it from console, and there it was, permission denied. As root, sound, as user, error. A quick browse through /dev/snd showed me that the audio group wasn't allowed to rw to /dev/snd/*

A restart of devfsd fixed all. If you use fixed nodes then chmod fixes it. If you use devfsd and remember chmodded settings, chmod fixes it. If you use devfsd, edit your devfsd.conf to handle /dev/snd entries properly (make it 0660 and put yerself in the 'audio' group) Dunno yet about the new udev though.
