[mythtv-users] DSP Sound Question

[Chris Ogles]

/dev/dsp is a link to /dev/sound/dsp  I don't think sound would work at
all if i was to delete /dev/sound ?  I forgot to mention in the orginal
message that I have tried /dev/dsp and /dev/sound/dsp both produce the
same error.  I have just emerged Freevo and it works sound in all but I
would much rather get Mythtv working.  I really like this app better than
freevo.  Any thoughts?
