Graham,

 

I believe that I have corrected the unstable audio level issue.  In addition to sudo apt-get autoremove pulseaudio, I installed sudo apt-get install gnome-alsamixer, then issued gnome-alsamixer to set the level controls. This apparently caused a conflict with existing alsamixer and alsactl store files and functions? 

 

That said, having removed gnome-alsamixer has allowed Ubuntu’s alsactl store to set and maintain consistent audio levels that remain following restarts.

 

Thank you for your help!

 

Bill, WA8WG

Bill,

I think you'll find that "alsactl store" saves the mixer parameters to a file (/var/lib/alsa/asound.state) and then you have to read them back in with "alsactl restore".  I don't think it's automatic, so you'd want to add the command to one of the startup scripts.

Unfortunately I can't help much with your rc.local problem.  I'd expect google has the answer if you can figure out the correct question to ask it.  Might be a path problem - something that wouldn't be an issue from an interactive shell, but no good at boot time.

Graham
