Dear Maintainer,

After upgrading from kernel 6.6.13-1~bpo12+1 to 6.7.12-1~bpo12+1, analog audio no longer works on my laptop. Pavucontrol only shows the various HDMI options for sound output.

Using an external USB interface works. Downgrading to 6.6.13 fixes the problem, so not a hardware issue.

It looks like the audio hardware is detected correctly, this part of the kernel log is identical in both versions:

[   16.161644] snd_hda_codec_realtek hdaudioC0D0: autoconfig for ALC3226: line_outs=1 (0x16/0x0/0x0/0x0/0x0) type:line
[   16.161743] snd_hda_codec_realtek hdaudioC0D0:    speaker_outs=1 (0x14/0x0/0x0/0x0/0x0)
[   16.161829] snd_hda_codec_realtek hdaudioC0D0:    hp_outs=1 (0x15/0x0/0x0/0x0/0x0)
[   16.161914] snd_hda_codec_realtek hdaudioC0D0:    mono: mono_out=0x0
[   16.161981] snd_hda_codec_realtek hdaudioC0D0:    inputs:
[   16.162045] snd_hda_codec_realtek hdaudioC0D0:      Dock Mic=0x19
[   16.162111] snd_hda_codec_realtek hdaudioC0D0:      Headset Mic=0x1a
[   16.162209] snd_hda_codec_realtek hdaudioC0D0:      Internal Mic=0x12


I don't know if it is significant, but the order of the interfaces is reversed in /proc/asound/cards; here is the 6.6.13 version:

 0 [HDMI           ]: HDA-Intel - HDA Intel HDMI
                      HDA Intel HDMI at 0xf7e34000 irq 53
 1 [PCH            ]: HDA-Intel - HDA Intel PCH
                      HDA Intel PCH at 0xf7e30000 irq 50

And 6.7.12:

 0 [PCH            ]: HDA-Intel - HDA Intel PCH
                      HDA Intel PCH at 0xf7e30000 irq 50
 1 [HDMI           ]: HDA-Intel - HDA Intel HDMI
                      HDA Intel HDMI at 0xf7e34000 irq 53

There are quite a lot of differences under /proc/asound, I'm not sure where to look for interesting differences.

Thanks for your time!
