MotoMod :Having problem with Audio greybus protocol

Are you going through the Moto High Speed bridge, or using the PHY lines directly for i2s?

Could you provide MuC logs?

Thanks alot for your response.

Right now, i am using I2S lines from phone Connector directly. [Made Dip Switch A2 as High on Mod]

device_i2s_start_receiver_port function is called when i start playback from Moto Z phone. After that i am not receiving any command even if i stop player from application or changing volume keys of Moto Z.

Here are the logs of MuC.

Stupid question, are you registered for device_i2s_stop_receiver?

Do you have logs of the stop, we're curious if the lower level greybus is being called but not making it to your handler somehow.  If that's actually the complete log including stop, this is very interesting...

The problem is resolved.

Actually i have already registered for device_i2s_stop_receiver call. But the problem is with device_i2s_start_receiver_port API.

Due to a stupid bug, it was hung there. After fixing it, i am able to receive all next commands perfectly even stop also.

Thanks very for much.

Cool, anything worth sharing for others?
