2019-02-22 08:48:16 Hui Wang 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.
