I am running FriendlyCore (Ubuntu 18.04.1 LTS 4.4.143). If I try to stream audio over bluetooth (a2dp) the sound is unrecognisable jitter. blue-alsa (a2dp profile provider for bluez) is reporting missing RTP packets.
It seems bluetooth stack is losing a bunch of packets.
When searching around I have found that some other SBC are experiencing similar problems on broadcom bluetooth/wifi combo controllers due to how Linux handles things. Apparently for those other SBCs it help to disable Wifi.
I have disabled Wifi using rfkill but it does not help the situation one bit.
Any help on how to solve this would be much appreciated. For instance, is there a better way to disable Wifi (more on a driver/kernel level)? Or maybe there are some parameters that can be set on Bluetooth/UART part that can improve the situation?
