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 On Wed, Jul 30, 2008 at 4:10 PM, Tinco Andringa <mail@xxxxxxxx> wrote: > > Hello, > > I am a bit new to this so please bear with me.

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 > > --- In reply to: --- > Clemens Ladisch cladisch at fastmail.net > > Thu Jul 24 12:04:48 EDT 2008 > > edro Ferreira wrote: >> 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 > } > } > } > }, > > > > HTH > Clemens > > _________________________________________________________________ > Express yourself instantly with MSN Messenger!
