Hi Theo,
in the 4a json config file the only available protocol for voice call is sco, but no audio is played.
Should I change other configuration?
Do you have kingfisher expansion too? Can you give me your 4a configuration?
Thank you.
Regards,
Francesco

Hi Francesco,
A2DP is the bluetooth profile for high quality audio (music playback). SCO is a bluetooth transport protocol used by the HFP/HSP bluetooth profiles for bi-directionnal low-latency audio. HFP/HSP are mainly used during telephone calls/VOIP sessions.
On AGL, your device should switch between A2DP and HFP/HSP when you make a telephone call. When the call ends, it should go back into A2DP for media playback.
I tested this to work correctly on Guppy on a M3ULCB board. Depending on your distro, this should either be handled by bluez-alsa or by a pulseaudio instance. You could try to look in that direction.
Best regards,Théo

Objet : Re: [H3ULCB + KF] Bluetooth audio problem with Guppy 7.0.3Hi all,
analysing the problem, I can say that audio playback works if the protocol is "a2dp" while it doesn't work with "sco" protocol.Can it be a configuration problem or is there an other problem?
Thank you.
Francesco
