Could anyone please give me a step-by-step guide to setting up my
m-audio 2496 to capture from the S/PDIF? I am trying to record into
either Audacity or Ardour, but cannot 'find' any sound.
I can route data using Envy24Ctrl so that the digital mix bars on the
L/H side are active, but cannot capture sound using applications. I'm
guessing therefore that alsa is set up incorrectly.
Using Audacity, under Edit->Preferences, only /dev/dsp is visible (I
cannot select any other interface). Recording just produces a flat line.
In Ardour (via jack), I cannot get anything to appear on the v/u bars
despite selecting alsa_capture1 & 2.
The interface works fine in winXP, so it's something I'm doing wrong.
So, can anyone help me to get the sound from my interface to audio
applications?
Thanks,
Rob Jackson

i don't know this device well at all, but under ALSA it is almost
certainly a separate subdevice from the main audio i/o. check the output
of "aplay -l"
ALSA represents most distinct i/o sections of an audio interface as its
own subdevice, since its typically clocked independently of the rest of
the card.

Maybe you forget to select the SPDIF Master Clock in Envy24Ctrl
Hardware Settings tab ?
Actual Rate must show S/PDIF.

If I recall, the digital input signals are not on 1 & 2 (those are
analog), try some of the other inputs (might be 3 & 4). It's been a
while since I've used the 2496...
Also make sure you've got your master clock set right (for SP/DIF, not
the A/D sampling rate)

it took me hours of googling, and i finally found this. i don't know if
it's the only or the best method, or if it'll work for you, but it did
for me.
1) i put this on my .asoundrc:
pcm.ice_spdif
{
type plug
ttable.0.8 1
ttable.1.9 1
slave.pcm {
type hw
card 0
device 0
}
}
2)
then try
ecasound -i alsa,ice_spdif -o alsa,plughw:0
to monitor your spdif inputs from the analog outputs, or
ecasound -i alsa,ice_spdif -o test.wav
to record to a file
3)
remember to set the clock input to spdif from envy24control
