The firmware does not provide any information for capture streams via the shared pipeline registers.
To avoid reporting invalid delay value for capture streams to user space we need to disable it.

Thanks!
[1/1] ASoC: SOF: ipc4-pcm: Delay reporting is only supported for playback direction commit: 98db16f314b3a0d6e5acd94708ea69751436467f
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
