From: Jan-Marek Glogowski glogow@fbihome.de Date: Sun, 15 Sep 2019 16:57:28 +0200 Subject: [PATCH] ALSA: hda/realtek - PCI quirk for Medion E4254

The laptop has a combined jack to attach headsets on the right. The BIOS encodes them as two different colored jacks at the front, but otherwise it seems to be configured ok. But any adaption of the pins config on its own doesn't fix the jack detection to work in Linux. Still Windows works correct.

This is somehow fixed by chaining ALC256_FIXUP_ASUS_HEADSET_MODE, which seems to register the microphone jack as a headset part and also results in fixing jack sensing, visible in dmesg as:

-snd_hda_codec_realtek hdaudioC0D0: Mic=0x19 +snd_hda_codec_realtek hdaudioC0D0: Headset Mic=0x19

[ Actually the essential change is the location of the jack; the driver created "Front Mic Jack" without the matching volume / mute control element due to its jack location, which confused PA. -- tiwai ]
