Hey everyone,
I am using a odroid c2 board with Armbien Buster image. I have a cheap bluetooth dongle and a usb sound card connected to the board. I am trying to use the board as bluetooht to aux input for my car. The board is working as expected when the a2dp profile is in use. But as soon as i place or receive a phone call i am getting garbage sound(garbage meaning a bunch of click like sound) after a while my phone drops the bluetooth connections and gives the sounds to earpiece on the phone. Also when the phone call places my syslog gets filled with "Bluetooth: hci0: SCO packet for unknown connection handle 0"
I am using bluez5, alsa and pulseaudio stack as for software. I tested this setup in another laptop with the same dongle and usb sound card and I am not having any issues. At this point I am really confused to if this is a harware or software issues. Hopefully someone here might help me out.
