For sure if it might help you: WL1837 from TI:

> Can you elaborate on how to configure it like that?

The commands I needed to do were vendor specific, so they may not
correlate directly to your chipset.
Also, although we started with similar symptoms (no audio via headset
profile), the cause of my issue could be quite different from yours.
As Tanu pointed out you had issues with the headset profile remaining
connected.
