If anyone has any objections, please let me know. ------------------ From: Hui Wang commit c8c6ee611926685a7d753409e0a6e48b9e1b8748 upstream. It is reported that there's a constant background "hum/whitenoise" in the headset on the Lenovo X1 machines with the codec alc285, and it is confirmed that if we run the command below, the noise will stop. sudo hda-verb /dev/snd/hwC0D0 0x1d SET_PIN_WIDGET_CONTROL 0x0 Then I consulted this issue with Kailang, he told me the pin 0x1d on this codec is used for PC beep in, the noise probably comes from this pin and we can also disable the PC beep in passthrough, then the PC beep in will not affect other sound playback.
