On Qualcomm Audioreach setup, some of the audio artifacts are seen in
both recording and playback. These patches fix issues by
1. Adjusting the fragment size that dsp can service.
2. schedule available playback buffers in time for dsp to not hit
under runs
3. remove some of the manual calculations done to get hardware pointer.
With these patches, am able to see Audio quality improvements.
Any testing would be appreciated.
This totally breaks audio on SDM845, and often results in a hard-crash
to crashdump mode on my OnePlus 6.
Its not possible.. as SDM845 is Elite DSP architecture, all of these
patches changes are very specific to Audioreach DSP architecture.
Could you please share the crash logs if you have any. It highly likely
that something else is triggering the hard-crash that you reported.
thanks,
Srini
Unfortunately I can't get UART logs right now. But I imagine this is
reproducible on RB3.
Kind regards,
thanks,
Srini
Changes since v2:
- dropped patch which is causing regression with pluseaudio.
- setup period sizes only for capture path
- fix underruns/overruns in dsp pipelines.
- add fixes tag
- add patch to fix buffer alignment
Changes since v1:
- added new patches to fix the fragment size, pointer
calculations
- updated to schedule only available buffers.
