Bluetooth A2DP issue on dragonboard 410c



I am facing Bluetooth A2DP issue on dragonboard 410c with a custom lvds panel. The audio starts on bt headset and stops after a second. Whereas , a2dp works fine when default hdmi panel is used instead of our custom panel.

Major change in device tree is to select dsi2lvds chip instead of adv7533.

please advise.


@arjun I’m afraid that I haven’t worked with a 410c in over 2 years, and haven’t the faintest idea about how the lvds relates to a2dp, except that the adv7533 receives i2s as an audio sink. I think you’ll need to look carefully at all of your audio routing, which I recall being incredibly (overly) complex on qualcomm devices.

Is it on Android or Linux (Debian, RPB) ? do you have any event in your dmesg or logcat/varlog when the audio stop ?
