[BUG] ALSA: hda/realtek: SSID 1458:a194 is shared by different Gigabyte ALC897 front-panel layouts

[Marcin Krycki]

Hi,

I found an issue with the recent ALC897 quirk for subsystem ID 1458:a194:

  SND_PCI_QUIRK(0x1458, 0xa194, "H610M H V2 DDR4",
                ALC897_FIXUP_H610M_HP_PIN)

My system:
- Board: Gigabyte B550 GAMING X V2
- Codec: Realtek ALC897
- Subsystem ID: 1458:a194

So my board uses the same subsystem ID as the one matched by the quirk above.

On my board this quirk is incorrect:
it forces pin 0x19 to HP out, but on this board 0x19 is the front microphone
pin and headphones are connected to 0x1b.

With the quirk applied:
- front microphone is detected as headphone
- front microphone does not work
- plugging only the microphone mutes speakers as if headphones were present

After removing the quirk match for 1458:a194, front panel behavior is correct:
- mic only: works
- hp only: works
- mic + hp: works
- mic only with hp unplugged: speakers remain active

This suggests that subsystem ID 1458:a194 is shared by at least two different
Gigabyte boards with different front-panel ALC897 layouts, so matching this
quirk only by SSID is too broad.

I am not sending a patch because the quirk may still be correct for the H610M
board it was added for. But the current SSID-based match causes regression on
Gigabyte B550 GAMING X V2.

Same issue here. After a recent kernel update from 6.19.10 to 6.19.11
(Arch Linux), I realized my mic port had become another headphone out.

Pin 0x19 (the physical Front Mic jack) is re-tasked as a second
headphone output, and the microphone input disappears from the
available sources in the system.

Prior to this patch (tested on kernel 6.19.10), auto-config correctly
identified the separate pins:
  inputs: Rear Mic=0x18, Front Mic=0x19
  hp_outs=1 (0x1b)

With this patch applied:
  inputs: Mic=0x18
  hp_outs=2 (0x1b, 0x19)
  Front Mic (0x19) is missing from inputs.

Manually re-tasking Pin 0x19 back to'Microphone' via hdajackretask
restores the expected behavior.

Hardware: Gigabyte B660I AORUS PRO DDR4 (rev. 1.x)
PCI SSID: 1458:a194
Codec: Realtek ALC897

OK, I'm going to revert the commit.  The fix patch looks dubious and
needs to be revisited.
