[alsa-devel] [PATCH] ALSA: hda - Introduce "Headset Mic" name
by David Henningsson 21 Mar '13

21 Mar '13

Headset mic jacks, i e TRRS style jacks with Headphone Left, Headphone Right, Mic and GND signals, are becoming increasingly common and are now being shipped by several manufacturers. Unfortunately, the HDA specification does not give us any hint of whether a Mic pin belongs to such a jack or not, but it would still be helpful for the user to know (especially if there is one TRS Mic jack and one TRRS headset jack). This new fixup causes the first (non-dock, non-internal) mic to be a headset mic jack. The algorithm can be later refined if needed.

The binding says that clock-frequency is optional if 'clocks' is provided, but here you list both. You should probably have two examples. -- Timur Tabi
