Thanks to the advice of someone else on the list, I think I have my 
sound card set up properly. However, I receive errors while trying to 
watch Live TV, and then exiting from LiveTV:

connecting to backend server: 127.0.0.1:6543
adding: lotus.njit.edu as a player 1
Unable to open mixer: '/dev/mixer'
adding: lotus.njit.edu as a player 0

Could not open audio device: /dev/dsp
Changing from None to WatchingLiveTV
Cannot open DSP '/dev/dsp', dying.
Could not detect audio blocksize

Over/underscanning. V: 0.000000, H: 0.000000, XOff: 0, YOff: 0
Using XV port 61

Here are the permissions on the two dvices mentioned:
$ ls dsp -l && ls mixer -l
lr-xr-xr-x    1 root     audio           9 May  8 11:24 dsp -> /dev/dsp0
lr-xr-xr-x    1 root     root           11 May  8 11:24 mixer -> /dev/mixer0

I tried changing dsp to group audio and making sure I was a member of 
audio, but it did not seem to make a difference. (Later, I noticed that 
all users have read and execute permissions anyway).

How does everyone else have their permissions set up?

Thanks in advance,

Joe
