Yes I can confirm that this fixes the errors which I was seening with asoc/for-5.11: Tested-by: Hans de Goede <hdegoede@redhat.com> Regards, Hans

[1/1] ASoC: pcm: send DAPM_STREAM_STOP event in dpcm_fe_dai_shutdown commit: bb9dd3ce6177e1f8cf01b0d45e6bd9b93f656bd0 All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted. You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail. Thanks, Mark

A recent change removed the call to send the DAPM_STREAM_STOP event in dpcm_fe_dai_shutdown. But this causes a regression when a PCM prepare is not paired with a hw_free. So, add the DAPM_STREAM_STOP event back to dpcm_fe_dai_shutdown() to fix this. The new sequence would be: soc_pcm_prepare() -> SND_SOC_DAPM_STREAM_START soc_pcm_hw_free() -> soc_pcm_hw_free() -> SND_SOC_DAPM_STREAM_STOP dpcm_fe_dai_shutdown() -> SND_SOC_DAPM_STREAM_STOP Note that the DAPM_STREAM_STOP will be called twice but it seems harmless.
