This is more of an issue report than a support request. The fact that kernel 5.19.1 works is useful information that can potentially be used to bisect where this regression happened.
Similar issue is reported here: Call audio quality on PinePhonePro is problematic for others (#249) · Issues · manjaro-arm / issues / Pinephone / Phosh · GitLab
I would probably comment on that issue with this information to indicate that audio on the ppp has regressed.
Maybe also test this solution (use pipewire instead of pulseaudio)
