Hi,
I just remembered this post from the alsa-devel list from last year that
said several Yamaha and Roland devices may work through a patch (which I
believe should have found it's way into Alsa 1.0.28):
http://mailman.alsa-project.org/pipermail/alsa-devel/2013-June/063475.html
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 -l
**** List of CAPTURE Hardware Devices ****
card 0: PCH [HDA Intel PCH], device 0: ALC272 Analog [ALC272 Analog]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 1: INTEGRA7 [INTEGRA-7], device 0: USB Audio [USB Audio]
Subdevices: 1/1
Subdevice #0: subdevice #0
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
With different settings, arecord tells me that S32_LE and 44100 are the
only available format and rate. The "Recording WAVE..." message appears
instantly, the error message appears after the 10 seconds. The wave file
then exists with a header but no audio content.
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?
Mirko
