[GTALUG] (Fwd) Re: Ubuntu Studio: Sound not working in all applications

[Paul King]

Some other oddments of the sound on my system:
The Ubuntu online docs suggested I run
   aplay /usr/share/sounds/alsa/Front_Center.wav
as a "fail-safe" audio file that is touted to work in all configs. It worked    
when: 
   a) I was logged on as root on a console (ie, one of the ALT+# screens); 
   b) when I logged onto a console with my joeuser account (as myself) and ran
      the command with sudo.
It did not work when logged in as myself, as myself on X-windows, or sudoed in 
X-Windows under my account, nor did it work if I logged on to X-windows as 
root.

In summary, logging in as root in a TTY has the best sound right now.

No need to apologize. If it is the PCM channel, then I don't know how to 
access its information to know if it is muted or not. I noticed that alsa was 
installed but not running (I did a ps | grep as root). Pulseaudio was actually 
running. I didn't know it was a wrapper for Alsa. It appears to be standalone 
going by the docs (I don't see alsa or OSS listed as a pre-requisite or a 
system requirement).
