Sorry if this is a too obvious question, but cant get my head around it.
Im using Patchbox and Audacity, trying to record something.
Is it it not possible to adjust the INPUT LEVEL of the Jack Input in the system?
In Audacity the Input level gain is also grayed out.
Alternatively, I tried this as stated elsewhere:
arecord -D hw:pisound -c 2 -r 48000 -f S16_LE | tee recording.wav | aplay -D hw:pisound
but it always gives me back:
aplay: main:788: audio open error: Device or resource busy
arecord: main:788: audio open error: Device or resource busy
Thanks for any hint!
