description |
Following on bugzilla #1648448. There's a constant background "hum/whitenoise" in the headset. The tone and level change whenever something changes on the LCD screen (window resize, GNOME expose, click/drag a window around the screen). Muting the headset using Fn+F1 makes the "hum/whitenoise" go away. Unmuting the headset brings the noise back. |
[Impact]
It is reported that there is constant noise on lenovo X1 machines, and after
investigating, I found this issue will happen on all Lenovo machines with the
codec alc285.
[Fix]
According to Realtek's comment, the noise comes from PC peeb in, after
disable this pin or disable the passthrough of this pin will fix the
problem.
[Test Case]
After applying this patch, we play sound on Lenovo P52, P72, X1 carbon and X1
Yoda2, no noise anymore. And this patch is confirmed to work by many other
users too (https://bugzilla.redhat.com/show_bug.cgi?id=1660581,
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1805079/comments/38).
[Regression Potential]
Low. This patch only apply to several lenovo machines, and it is tested
by many users already. |
