I have been trying to solve this crackling sound happened after a phone call. the phone call was carried out via Android Auto. Before the phone call, music is very clear, echo cancel was great and the mic sound is clear from the receiving end. After phone call, the crackling sound (pip, pop, crack) appear. After OPA immediate reboot, the crackling sound appear straight at the beginning. After power off the OPA for sometime and then start the OPA, the crackling sound disappear. the crackling sound reappear after a phone call.
OPA version - 13 pro
Bluetooth - version 4 and not broadcom version
disabled the WIFI and onboard bluetooth
Hifiberry Digi+ Pro2
Android Auto running on Huawei phone. - no such issue with original car audio system.
no other peripheral attached when I carried out this testing.
I hope there is a solution available. it was a journey to learn Linux and other hardware integration.
Help please.
