Sorry for being asleep at the switch, tax time hit me squarely between
the eyes. :/
The problem I'm seeing is that pulse can select the spdif input on both
devices, but I never hear any sound. I've also tried using alsa via rec
(from SOX) to record from various hw: devices with no joy. Also using
ALSA devices from Audacity (which is what I started with in the first
place.)
HOWEVER, I was able to get at the optical audio in on the SIIG device
with the following command:
arecord -c 2 -f S32_LE -r 48000 -D dsnoop:CARD=Audio,DEV=1 trythis2.wav
And then I investigated the "plughw" interface, and this worked too:
arecord -c 2 -f S16_LE -r 48000 -D plughw:CARD=Audio,DEV=1
trythisPLUG.wav
So at least I can investigate that, and read up on using dsnoop and
plughw devices with Audacity.
The Sound Blaster HD, though, didn't have the same luck -- it is still
flatline when I view the dsnoop: device recording .wav files with
audacity, as well as the files from arecord on the plughw devices.
The output of arecord -L is in my .sig.
I see also "dmix" devices on the SIIG device, I will now investigate
those for optical spdif playback on the SIIG device, and the Sound
Blaster HD device if I have a chance. The X-Fi device plays through the
optical spdif connector as expected.
Thank you!
