The patch
ASoC: Intel: Skylake: set the resume point to LPIB
has been applied to the asoc tree at
git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git
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

In system suspend, the firmware pipelines will be deleted and there is no need to save the pipeline context. Driver will save the DPIB and LPIB pointers in suspend.
In system resume, the firmware pipelines will be created again and the RD/RW pointers in the Firmware buffer points to the base address. So need to fetch the non-played data again to firmware buffer. LPIB indicates the HW rendered position.
Instead of setting DPIB as resume point, set it to LPIB to restore from the HW render position so that DMA would fetch the non-played data one more time.
