Hi,
I'm trying to work out how to record from an S/PDIF input
using a Terratec 7.1 Space (Envy24 based card, supported by
ICE1724 Alsa driver). I simply can't work it out.
Under Windows it's necessary to use the Terratec control
panel to select S/PDIF as the recording source (rather
than the analogue mixer/sources). What I think I should
do under Linux is something like:
$ arecord -f dat test.wav -Dhw:0,1
This gives:
Recording WAVE 'test.wav' : Signed 16 bit Little Endian, Rate 48000
Hz, Stereo
arecord: set_params:901: Sample format non available
$ arecord -l
**** List of CAPTURE Hardware Devices ****
card 0: T71Space [Terratec Aureon 7.1-Space], device 0: ICE1724 [ICE1724]

Subdevice #0: subdevice #0

While you're waiting for a real reply, try this ...
arecord -L
Should show a list of PCM device names, on my box, I see "spdif" and
"iec958" in the list.
arecord -f dat test.wav -D spdif
might work, I don't actually have a working spdif input.
Thanks for the suggestion. This gives the same 'non available'
error as above. Maybe these aren't recording aliases?
Contents of 'arecord -L' are attached.
I've just confirmed that an analogue loopback recording works
if -D is not specified, whereas -Dhw:0,0 (which I think should
be the analogue device) gives the 'non available' error.
