 [REGRESSION] 6.7.0: ASoC: SOF: refactoring breaks sof-rt5682 audio on
 chromebook; successfully bisected

I'm relatively new here, first time reporting a regression, so apologies in 
advance if I'm doing something wrong.

I'm using Arch Linux (linux-mainline kernel) on my chromebook Acer Spin 713-2W 
(Voxel), and after upgrading linux-mainline from 6.7-rc4 to 6.7-rc5 the audio 
setup isn't working anymore. Firstly I suspected its some changes in the sof-
firmware, yet got no luck in upgrading sof-firmware (2023.09.2 -> 2023.12). 

On certain chromebooks, audio setup needs custom ALSA ucm confs [1], but after 
contacting the chromebook-linux-audio developer [2], I think it's not a conf 
problem, but rather a kernel regression.

After hours of bisecting, the first bad commit 31ed8da (ASoC: SOF: sof-audio: 
Modify logic for enabling/disabling topology cores) ensures the regression. 
demsg log pasted below:

Steps to reproduce:

- Run chromebook-linux-audio script [2] (this would install custom sof-rt5682 
ucm confs [1] into /usr/share/alsa/ucm2/conf.d/sof-rt5682 and write a line 
`options snd-intel-dspcfg dsp_driver=3` to /etc/modprobe.d/snd-sof.conf)
- Reboot, gets audio working on kernels before 31ed8da
- Install latest stable kernel (6.7.3), audio broken
- Install latest git kernel (6.8-rc2), audio broken
- Revert 31ed8da, build upon latest linux-git (6.8-rc2), audio working

Apologies for my busyiness that I should have reported it long before the 
regression enters stable and lts, but sadly linux-lts (6.6.13) seems to be 
affected too [3].

Please let me know if there's any other thing that I can help debugging.
