@Akirafubuki The issue with builtin bluetooth adapter dying while using a2dp audio was known for a long time.
Still no fix.
https://github.com/raspberrypi/firmware/issues/887
I think it would be good if all the affected people could write in that issue confirming they have it,
maybe this way it can get enough attention so jamesh's (rpf) lazy ass finally gets cypress' lazy asses to fix the issue.

Personally I've been using a cheapo usb bt dongle (CSR) for more than a year already.

Edit: the new firmware fixes bluetooth LE issues, but sadly not a2dp issue.
