I thought I'd give it a try: I own a Roland Integra-7 sound module
which is supposed to be able to send it's output over USB. I cannot
get it to output any sound, though. Here's what I'm trying to do
(USB mode is set to "Vendor (Audio + MIDI)" on the device):
[...]
mir@robotnik:~$ arecord -d 10 -c 2 -f S32_LE
-r44100 -D hw:INTEGRA7
test.wav
Recording WAVE 'test.wav' : Signed 32 bit Little Endian, Rate 44100
Hz, Stereo
arecord: pcm_read:2031: read error: Input/output error
[...]
Is there anything I'm doing wrong, or did I
misinterpret the post on
alsa-devel and a quirk is still needed for the Integra?
I think the quirk is there to tell the kernel module that it can handle
the vendor/product IDs.. so if its listed by arecord -l then that's OK.
The following post (by Clemens) lists hardware capabilities, after
compilation:

Would you post the output of the program in the email thread that I linked?
Perhaps there's an ALSA format issue or so.
