Audio will pass to ALSA.
In this version of android image (android 7.1.1 V0.1 beta 2018-5-29), audio works fine.
In Linux need some hack to enable HDMI IN function and you can capture the audio from ALSA

Thank you it was very helpful ,

Do you know what HW video acceleration encoding supported by BP W2?

H264, H265 But there is no library for Linux to HW video encoding. Maybe you have to ask official about those support.
