Hello, I have the openauto pro 2.0 running and everything works great but I cant resolve the issue of callers hearing themselves when talking in the vehicle over bluetooth. I thought that's what the echo cancellation was supposed to take care of, and adjusting the Pulse Audio sound properties in Raspbian the input and outputs say "Echo Cancelled" but the mic still pics up the speakers (I assume) and the caller hears their own voice about a second later. I have tried adjusting the latency offset but it doesnt seem to change anything. I also notice that when my phone connects to BT, my phone shows up in pulse audio (LG V30) but does not say echo cancelled... Love everything you have done here and the system would be perfect if I can get this issue figured out. Thanks!
