All,

I sent an email a while back about problems getting ALSA to work.  I
have OSS working in mythtv and ALSA works in both mplayer and xine, but
I get no sound when specifying either "ALSA:default" or "ALSA:spdif"
with or without AC3 passthrough.  I'm using the spdif outputs on an
Maudio Delta DIO 2496.  Here's the output of 'mythfrontend --verbose
playback,audio'

I had some trouble getting my Delta 410 to work. Finally got it to work by putting:

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
pcm.!default {
   type plug
   slave.pcm iec958
}

pcm.ice1712 {
  type hw
  card 0
}

ctl.ice1712 {
  type hw
  card 0
}

pcm.ice1712_spdif {
   type plug
   ttable.0.8 1 # S/PDIF left...Delta 9
   ttable.1.9 1 # S/PDIF right...Delta 10
   slave.pcm ice1712
}
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

in my /etc/asound.conf file. I then told Myth to use "ALSA:ice1712_spdif" and it worked.

The Delta410 has ten connections on it. I don't know how many your 2496 has. You may need to play around with those ttable entries to find the right values for your card.

While struggling to get it working, I also played around with the envy24control tool, but I don't remember if there were any settings in there which needed changed.

Hope this helps.

John
