ALSA: hda - Fix headset mic input after muted internal mic (Dell/Realtek)
By trial and error, I found this patch could work around an issue where the headset mic would stop working if you switch between the internal mic and the headset mic, and the internal mic was muted. It still takes a second or two before the headset mic actually starts working, but still better than nothing. Information update from Kailang: The verb was ADC digital mute(bit 6 default 1). Switch internal mic and headset mic will run alc_headset_mode_default. The coef index 0x11 will set to 0x0041. Because headset mode was fixed type. It doesn't need to run alc_determine_headset_type. So, the value still keep 0x0041. ADC was muted.
