Hi Marcel, Another thing worth to say is that so far I found the pattern is like the following: If the sender side is CSR chipset USB dongle with Bluez and receiver side is also Bluez, it will most likely read all zero. If the sender side is CSR chipset USB dongle with Bluez and receiver side is NOT Bluez, it seems OK. If the sender side is another chipset and receiver side is also Bluez, it seems OK, but voice is a little choppy.

There is no guarantee that it does the right job. Some devices might send silence if the Headset or Handsfree profile is not fully setup.
