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.
With this series, the choppy (robotic) capture when using pipewire
appears to be fixed (pulseaudio worked before).
Playback is still choppy (heavily distorted), though, and now it also
appears to be too slow.
I tested using pw-record and pw-play (and mpv) on the T14s (6.14-rc3).
Retested this morning and realised that playback is only choppy (and too
slow) while I have pavucontrol open. That would be nice to fix if
possible, but this is still a great improvement since pipewire was not
usable at all before these changes.

Hmm... Scratch that.
This series apparently breaks pulseaudio instead.
Thanks for trying out pulseaudio, I will try to reproduce this with my t14.

Too fast playback on the T14s with mpv, and after I stopped it I wasn't
able too play any audio anymore. And systemd complains about a stop job
running for long when rebooting. Similar issues on the X13s.
