Questions about bluetooth (A2DP) with vg's CM 10.1 ROM.

I have a Sony MW600 headset which supports both the Headset and Multimedia profiles. This problem existed on the earlier builds of CM10.1 that I tested.

The headset works fine on my phone (though Bluetooth is off on my phone while using it on the tablet).

I am using the headset to listen to and control music with Google Play Music. There seems to be an issue with the Bluetooth driver / connection because:

- There are a ton of "vendor op - 7" messages in the log file (see below). They occur every 14 to 70 ms, in pairs. These are continuous while streaming audio to the headset. The process id 1392 is "bluetooth 1392 ... com.android.bluetooth".

- The audio cuts out periodically and seems to do it more frequently over time.

- The WiFi connection times out after a while (maybe from exhaustion of system resources?).

I found the following link doing a search but I don't know what it means exactly or if this would be patched in the CM 10.1 source:

https://github.com/M66B/cm-xtended/issues/27

And a few more results:

https://www.google.com/search?hl=en&q="vendor+op+-+7"+CM+bluetooth

So, my questions are:

1. If this is something that can be fixed in the CM build?

2. Are other people seeing better results with other Bluetooth headsets? I like the Sony I have because you can use any headphones with it (has a 3.5mm stereo jack).

And part of the log output showing the vendor op - 7 messages about a minute after a reboot:
