[LAU] Roland Integra-7 and Alsa 1.0.28

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
