Getting your soundcard to work, using Debian on non-i386 hardware, etc

problem with my soundcard

Postby lrsanches » 2021-02-02 15:23

Hello, guys!!

When playing music with volume above 50% the right speaker starts doing weird sounds, distortion I believe.
I've done my search, debian sound page, arch wiki, forums, nothing worked that's why I'm here.
And it's not a hardware problem, on my headset happens the same thing.
If someone have any suggestions please, HELP ME!!
Thanks.

This does not exclude a possibility of hardware problem - in fact, it looks like an effect of damaged HW.

Most probable HW-related reasons:
- damaged audio output socket: some models/types are directly switching the audio channels between internal speakers and external headphones, and they are often causing problems, distortions included.
- damaged coupling capacitor on the sound chip output.
- damaged output amplifier in the sound chip.

You can try to boot some other live OS from an USB stick and compare the results.

The problem may be in the driver, or search for the source in the settings (Pulse or Alsa, in that way).
