Bug Description
Hi,
When I play with the "output volume" in the sound settings panel, it sometimes make the sound become completely crushed (noisy, high pitch peaks).
It won't become normal until I set the mode to "Analog Stereo Output" first and then back to "Analog Surround 5.1 output" (or if I restart).
I tried this: https:/
In the end, options snd-hda-intel position_fix=1 in /etc/modprobe.
I also tried options snd-hda-intel position_fix=2 and the bug came back.
--> Can you make a fix so it works out of the box ?
Regards.
Sam

Thanks for your bug report. Actually, I think this is already fixed in later kernels.
You can verify this by upgrading your alsa drivers: https:/ /wiki.ubuntu. com/Audio/ UpgradingAlsa/ DKMS
