Have you tried changing the output configuration between best match, fixed and optimized, disable “allow passthrough” while you test.

my best guess from you log is the problem is here, I don’t know if this means the dongle doesn’t support the audio format used by kodi:

I have tried setting all methods but they still do not work. suspect that the kernel does not support the dongle？

When playing movies does can sound on Xbox Kodi, why is there no sound on Corelec? How to extract the kernel from Xbox Kodi and copy it to Corelec?

I don’t think Xbox runs on linux, so whatever audio driver it’s using there isn’t going to help in CE. It’s hard troubleshoot the headset without having it to work with. It may rely on some audio driver that’s not present or fully functional in CE-NG and/or linux 4.9.
