Hello,

the internal HDA codec (Realtek ALC269VB) of my Acer Aspire 4820G is no
longer detected since v6.16. Only the HDMI audio of the Radeon remains,
so the built-in speakers are silent. Everything up to v6.15.11 works 
(actually between 6.9 and 6.15.11 - 6.8 also does not work).

Hardware
   - Acer Aspire 4820G (2010), BIOS V1.25
   - Intel PCH HDA controller 0000:00:1b.0, codec Realtek ALC269VB
   - Switchable graphics: Intel (i915) + ATI Radeon (radeon), vga_switcheroo
   - ATI HDMI audio at 0000:01:00.1

Setup
   Xubuntu 26.04.1; kernels are the Ubuntu mainline builds from
   kernel.ubuntu.com/mainline (6.16.0-061600-generic etc.), except
   6.8.0-147-generic (Ubuntu). Kernel command line: quiet splash.
   Every test was a full reboot, a subset of them cold boots (power off).
   The pattern is fully consistent and reproducible.

Results
   good: 6.9.12, 6.11.11, 6.12.113, 6.14.11, 6.15.11
   bad:  6.16.0, 6.16.12, 6.18.57, 7.0.0-38
   also bad: 6.8.0-147 (Ubuntu), but 6.9.12 is good, so that could be an
   older, separate or related problem that was fixed for 6.9.
   No 6.16-rc builds were available in the archive, so I could not narrow
   it down further than v6.15.11 (good) -> v6.16.0 (bad).

Log on bad kernels (6.16.0)
   snd_hda_intel 0000:00:1b.0: number of I/O streams is 30, forcing 
separate stream tags
   snd_hda_intel 0000:00:1b.0: CORB reset timeout#2, CORBRP = 65535
   hdaudio hdaudioC1D0: no AFG or MFG node found
   (same for hdaudioC1D1, C1D2, C1D3)
   snd_hda_intel 0000:00:1b.0: no codecs initialized

Log on good kernels (6.15.11)
   The "number of I/O streams is 30" line is not printed, and
   snd_hda_codec_realtek binds:
   snd_hda_codec_realtek hdaudioC1D0: autoconfig for ALC269VB: 
line_outs=1 ...

Observation
   "30 streams" is what one would get from a GCAP value of 0xFFFF
   (ISS = OSS = 15), and CORBRP = 65535 is also all ones. This looks like
   the controller is not accessible (or still in reset/low power) when the
   driver probes it on 6.16 and later. This is only my interpretation of
   the numbers - please ignore, if it does not make sense.

Attached: dmesg (hda|codec|CORB), uname -r and aplay -l for 6.8.0, 
6.9.12, 6.15.11,
6.16.0, 6.18.57 and 7.0.0, plus alsa-info and lspci -nnk.

I am happy to test patches or answer questions.

One thing that we get to say to rarely:
Thank you very much to you and all the kernel developers for the great 
work and great dedication to FOSS software!

Thanks,
Florian
