just got a new Lumia 820 and paired my Sonyericsson bluetooth headset HBH-DS980 supporting the v2 A2DP bluetooth profile. Result is that phone calls are working but listening to music over bluetooth is not possible.
Doesn't the Lumia support the standard A2DP bluetooth profile ?
I have used the Headset with Sonyericsson phones, PCs and Android tablets for several yeards so I am bit reluctant to blame the headset in this case ...
Does the Lumia have a non-backwards compatible or proprietary bluetooth stack
In that case I would question the intelligence of the design ...
Solved! Go to Solution.
Restart of phone + restart of headset and voilá we have sound.
Otherwise OK except for a high pitched whining background noise.
It seems like windows phone is like normal windows, no driver & HW update possible without system restart
Should have thought of that before posting
