Michael, Could you review this patch? In woodduck there is a bt native process (such as pid=175 in comment 1). By default bt call use 8khz sampling rate (NB). When hfp profile 1.6 is used bt task need will use setparameters to change the sampling rate to 16 khz (wb). If bt task do not grant the permission there will be an error.
So this is something different from AOSP. They have their own way to handle Wideband speech?

Thomas, is this something that the bluetooth daemon will need to be able to do? Seems like a generally valid thing to do.
So far we only know that woodduck is using complete proprietary close source bluetooth stack, the stack has different architecture but supports the same Android Bluetooth HAL interface, and it supports wide band speech which needs to call audio library directly.

Or maybe let's check the status of Woodduck in m-c. Shawn, will the Woodduck patches have to be applied to m-c as well?
AFAIK, the current rule is that if the bug is general and can be reproduced on flame, we should apply to m-c. In general, we shall minimize the difference. I guess current bluedroid (KK based) does not handle wide band speech (HD voice), so the bug does not happen on m-c.
Per comment 12.
