The permissions you are listing are associated with the symlink, not the 
underlying device. (And they look unlike any symlink permissions I have 
ever seen ... on my systems, symlinks always show up as "lrwxrwxrwx" ... 
perhaps someone can clarify that part?)

Anyway ... check the permissions on the /dev/dsp0 and /dev/mixer0 . They 
need to be mode 660 (you need write permission in order to use /dev/dsp0 
for output) with group audio and the mythtv userid part of group audio. 
(Obvious other variants are possible, such as mode 666, but that's the 
setup I usually use.)
