FWIW, on my system everything under /proc/asound belongs to root:root,
therefore making sure the user running mythtv was in the audio group
didn't help. My personal solution was to add a command to a command the
local start up scripts to (a) change the ownership of that particular
file to root:audio, (b) chmod to 664 and (c) echo 192 into it.
