Messy failed attempt
Discarded the well intentions for now because of incredible problems getting the MBus CDC emulation to work.

UbarCDC will run in parallel with the CDC. Disc 6 is a self burnt disc with 15 tracks on it, each track is 5 minutes long and is just silence. UbarCDC will detect this disc and enable A2DP audio streaming as well as skip/prev controls.
