@plbossart @ranj063 It seems we call assign_hext_stream() and release_hext_stream() unbalanced. hda_link_dma_hw_params() -> assign_hext_stream() is called in hda_dai_hw_params_data(). However, hda_link_dma_cleanup() -> release_hext_stream() is called in hda_dai_hw_free(), hda_dai_suspend(), and SNDRV_PCM_TRIGGER_SUSPEND. Will it...

Yeah, it looks like a HW issue to me, too. It seems that rt711 can be attached sometimes but not always.

Maybe bus an USB sound card is the simplest way.

@poltpolt Can you check if https://github.com/torvalds/linux/commit/ab8d66d132bc8f1992d3eb6cab8d32dda6733c84 is in your kernel? If so, please revert it and test again.

@liquidev Can you run "sudo alsaucm reload" command and see if there is any error output?

This seems to be related to https://github.com/thesofproject/linux/pull/5074. I did some test today and confirmed that no issue on topic/sof-dev-rebase and broonie/for-next branch. And can reproduce the issue after applying https://github.com/thesofproject/linux/pull/5074...
