I agree the codec is terrible, they are using G.722 - Wikipedia which is 34 years old now
Wishful thinking you aren’t talking to the engineering team behind this. Google/Resound will not fix these issue because the new LE Audio protocol is already out. there is no reason to fix the old ASHA protocol and it has been deprecated / abandoned already. It has been on life support for a long time now…
I was afraid this was the truth, unfortunate really, for those that are/were having these issues and then were “dumped” google took to long to come on board with ASHA anyway, almost like an afterthought!
