Slackware 12.2 +snd-hda-intel


Greetings all,

I am using slackware 12.2 with a generic kernel and am having issues with my nVidia MCP51 built-in sound interface using ALSA.
While physically at the machine, everything works as expected. I'm able to load up alsamixer, play music with mplayer, etc. My issue rears it's ugly head when I log in remotely e.g. ssh or vnc. As my regular user when I run alsamixer I receive the following:

alsamixer

alsamixer: function snd_ctl_open failed for default: No such file or directory

However if I run sudo /usr/bin/alsamixer I have no problems.

Similar story if I run mplayer. As a regular user I see:
Code:

Video: no video
Starting playback...
A:   6.2 (06.2) of 196.0 (03:16.0)  0.3%
Whereas if I do sudo /usr/local/bin/mplayer I have no troubles.

I can live with doing this, but does anyone have any ideas? It's saying my user doesn't have permissions to use the device, but again if I'm physically at the machine my regular user has no problems with this.

Any input would be much appreciated!

Cheers,

g85
