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
