[alsa-devel] Persisting background noise on HDA Intel PCH (ALC3232)

Hello all,

On my Thinkpad x240, I am experiencing exactly the same bug as someone on the
x230 [0], that is I get clearly audible background noise on headphone and
speaker outputs unless I mute the Headphone/Speaker control or Master. In both
cases, a Realtek ALC on a Thinkpad is involved.

I have attached the alsa-info.sh output. The problems occur with plain ALSA
output, Jack or Pulse are not involved.

I have tried all suggestions mentioned in [0], and also tested all available
ALC-related model= parameters to snd_hda_intel, but the issue persists.

Muting all mixers on all cards didn't change anything either. Other Thinkpad
laptops with the ALC3232 codec are also affected by this bug, for example [1].

The bug makes the audio output unuseable for any serious purpose.

I would be very grateful if somebody could look into this (again?), and also
assist as far as I can.

Thank you & Best regards
-Jens.

PS. I'm sorry if this is not the correct place to report this, but the bug
tracker linked on the ALSA project home page seems to be down.
