I’m currently struggling on recording from the audio jack, which should be possible, no?
I installed Debian and am perfectly fine playing sound files with “aplay”, but using “arecord” to capture data from my microphone just produces static noise. I’d guess that I somehow need to switch from playback to capture but after hours and days of searching the internet and trying different things, I still made no progress.
So, can anyone of you help me with that? I hope it’s a simple task, just complicated by my inexperience.
