CarPlay Audio Issues with 9.x on iPhone 6s+
Have a Pioneer AVIC-8100NEX head unit connected to the 6s+ via USB. Had no issues prior to the 9.X updates using a iPhone 6. Upgraded both OS and Phone and since then have been having problems with either no audio output (thou UI says it's playing) or static (digital noise) screeching my speakers in stead of music. Problem persist on the iPhone after disconnecting and requires a reboot of the phone. After reboot connecting back to head unit works fine (don't need to reboot head unit). This happens almost every other time I connect the phone.
I am currently investigating turning off blue tooth and only using the tethered USB connection, thinking it might be a new conflict between BT audio and CarPlay audio corrupting the audio stack on the phone, but don't have enough data yet to say it makes a difference.
Is this a known bug, have been unable to find any information on the problem.
Not sure this is best place to post, didn't see a CarPlay forum.
