I am quite familiar with audacity and its capabilities, but I am having trouble playing back recorded signal from line in.
Audacity version 2.0.3
Intel motherboard (line out, line in, microphone) with old Pentium 4 1,7 GHz processor
Signal from a guitar combo with a line out output
Sound driver directly from Intel.
The problem is: when I record from a microphone input with a microphone, everything records ok and plays back.
When I use the line out from the guitar combo everything records ok, waveform is visible - matches the guitar playing.
But I can´t get it to play back. I press play and only a slightly audiable sound comes through the speakers.
When I record one track with microphone and one with line in, alongside (multi-track) only the signal from microphone can be properly heard.
I have not tried to connect the line out to microphone in. That did not cross my mind, in next step I will try that.
Raising volume on the Line in track only overdrives the signal.
