Hello,
The "No mixer elems found" error is normal. A for the rest, I guess
you are not correctly selecting the device for recording.
arecord --device=default:CARD=GT10 -t wav -f s16_le -r 44100 -c 2 test.wav
works for me :)
Good luck,
Pedro

Hello,
I am a bit new to this so please bear with me. I'm trying to get my Boss GT-10 to
work on my (arch) linux install.
I added the patch that was suggested in the post I reply to to my usbquirks.h and
compiled alsa using the guide on this site:
http://www.alsa-project.org/main/index.php/Matrix:Module-usb-audio with as only difference
that I configured with '--with-cards=all'.
After this my BOSS GT-10 was recognised by linux and I am able to play sound over it
using aplay. Recording however seems not to work. When I run arecord -L it shows all three
of my audio cards, including the bossgt, but when I do alsamixer -c 2 it gives the
following error: No mixer elems found. Using a command like arecord -d 5 -t wav test.wav
just gives me the sound recorded by the microphone in another soundcard. It could be that
it's just a matter of using -D to select the right PCM, but I'm not sure how to
find the right PCM.
I suspect this is the reason I cannot record, do you have any idea what goes wrong?
Another question more out of curiosity, why does the patch specify
USB_DEVICE(0x0592,0x00da) whilst the usb device as listed by lsusb has id 0x00db?
If I need supply any specific information
With kind regards and gratitude for the patch,
Tinco Andringa

OK, I've added the output as an attachment

Sorry for the delay.
Please try adding the entry below anywhere in sound/usb/usbquirks.h
and recompile the driver:
{
/* BOSS GT-10 */
USB_DEVICE(0x0582, 0x00da),
.driver_info = (unsigned long) & (const struct snd_usb_audio_quirk) {
.ifnum = QUIRK_ANY_INTERFACE,
.type = QUIRK_COMPOSITE,
.data = (const struct snd_usb_audio_quirk[]) {
{
.ifnum = 0,
.type = QUIRK_AUDIO_STANDARD_INTERFACE
},
{
.ifnum = 1,
.type = QUIRK_AUDIO_STANDARD_INTERFACE
},
{
.ifnum = 2,
.type = QUIRK_MIDI_FIXED_ENDPOINT,
.data = & (const struct snd_usb_midi_endpoint_info) {
.out_cables = 0x0001,
.in_cables = 0x0001
}
},
{
.ifnum = -1
}
}
}
},
