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:

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,

Though I have set up slack a few times with various sound cards... never had this issue before. Weird, but oh well.
