Noise and low volume


#1

I have a lot of noise and the output volume is low. It’s not the speaker because regular radio plays loud and clear.
My settings:
PCM/L16,
44.1 kHz,
128 bitrate.
But also other settings (MP3 mode) lead to the same noise and low volume.

The noise seems periodic with a period of ~1 sec. What could be the problem?
