From: Srinivas Kandagatla <srinivas.kandagatla@xxxxxxxxxx> 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.
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.
