[LAU] Boss GT-10

[Pedro Ferreira]

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

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.
