FWIW, the commit that introduced the fix is de96fcd8. Also the solution should consider a transition and not dropping the stream completely before configuring the other, otherwise errors may cause a complete disconnect just to switch between endpoints. Actually I would suggest configuring both endpoint since the beginning so that we only need to suspend/resume to switch between them, but I don't think many headsets would be able to handle this situation. -- Luiz Augusto von Dentz Computer Engineer -- To unsubscribe from this list: send the line "unsubscribe linux-bluetooth" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
