Hi All,
To test the code to dynamically switch between SST/SOF support on BYT/CHT from the kernel commandline I merged:
https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git/log/?h=for...
Into my personal tree (mostly Linus' master + some pending patches from myself).
After this I was getting the following errors in dmesg when using sound on a Medion E2228T laptop with a CHT SoC + NAU8824 codec:

Dropping the asoc/for-5.11 merge and just cherry-picking Pierre-Louis' changes for the dynamic switching makes these go away. So this seems to be caused by other changes in asoc/for-5.11.
So any clues where to start looking for this, or should I just bisect this?
Thanks for reporting this Hans.
The only thing that comes to my mind is Morimoto-san's series which modified snd_soc_dai_startup, but that was back in September and should be in 5.10-rcX
Will give it a try on my side as well.
I was able to reproduce this error with Mark's for-next branch on a CHT device w/ rt5640, and git bisect points to this commit:
a27b421f1d04b201c474a15ee1591919c81fb413 is the first bad commit commit a27b421f1d04b201c474a15ee1591919c81fb413 Author: Ranjani Sridharan ranjani.sridharan@linux.intel.com Date: Tue Nov 17 13:50:01 2020 -0800
ASoC: pcm: call snd_soc_dapm_stream_stop() in soc_pcm_hw_clean Currently, the SND_SOC_DAPM_STREAM_START event is sent during pcm_prepare() but the SND_SOC_DAPM_STREAM_STOP event is sent only in dpcm_fe_dai_shutdown() after soc_pcm_close(). This results in an imbalance between when the DAPM widgets receive the PRE/POST_PMU/PMD events. So call snd_soc_dapm_stream_stop() in soc_pcm_hw_clean() before the snd_soc_pcm_component_hw_free() to keep the stream_stop DAPM event balanced with the stream_start event in soc_pm_prepare(). Also, in order to prevent duplicate DAPM stream events, remove the call for DAPM STREAM_START event in dpcm_fe_dai_prepare() and the call for DAPM STREAM_STOP event in dpcm_fe_dai_shutdown().

I am not sure why this break the Atom/SST driver, this was reviewed and seemed legit - even required IIRC to deal with topology pipelines initialized on-demand. Reverting this patch restores functionality. I would guess it's the DAPM_STREAM_START that's now missing (or in the 'wrong' location) and causing issues?
Pierre-Louis, thank you for bisecting this.
Indeed the DAPM_START_STREAM call completely disappeared after the patch, which looks very wrong.
Yes that probably explains this issue.
Hans, can you confirm if indeed this is the same issue on your devices?
I've tried reverting the commit and I can confirm that asoc/for-5.11 works fine with the commit reverted.
Regards,
Hans
