I noticed on the device, this function returns: [ENCODING_PCM_16BIT, ENCODING_PCM_16BIT, ENCODING_E_AC3, ENCODING_AC4, ENCODING_E_AC3_JOC], but later when the player tries to initialize an AudioTrack with ENCODING_E_AC3 then the above crash happen.

It may be an OS level bug, but should you move this bluetooth check before the getCapabilitiesInternalForDirectPlayback call?

Media

Any dolby digital stream. But I cannot provide one.
