[PATCH v2 0/2] ASoC: intel: atom: 2 bug-fixes for the atom SST driver
Hi All,
Here is v2 of my bugfix series for the ASoC Intel Atom SST driver.
The patches are unchanged except for adding Pierre-Louis' Acked-By and adding a fixed (subject fixed) version of the Fixes: tag which Pierre-Louis suggested.
The first patch fixes a bug which is causing audio to now work with pipewire and both Fedora and Arch Linux are moving towards using pipewire as the default sound-server.
As such it would be good if we can get these 2 bugfixes added to a 5.12-rc# release.
Regards,
Hans

The SST firmware's media and deep-buffer inputs are hardcoded to S16LE, the corresponding DAIs don't have a hw_params callback and their prepare callback also does not take the format into account.
So far the advertising of non working S24LE support has not caused issues because pulseaudio defaults to S16LE, but changing pulse-audio's config to use S24LE will result in broken sound.
Pipewire is replacing pulse now and pipewire prefers S24LE over S16LE when available, causing the problem of the broken S24LE support to come to the surface now.

The media and deep-buffer DAIs only support 48000 Hz samplerate, remove the 44100 sample-rate from their descriptions.

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
