I sometimes play music by enabling bluetooth on my phone and connecting it to my car audio ( Pionner) altough music volume and quiality is not what I expect but something that is more annoying is that music sound is intruptted in a random time. very annoying. I checked All setting in my phone and car audio and everything seems correct.
Same here, i also have a pionner head unit. It is working perfectly with my Nexus 5 so i don't the car stereo is the problem. I have this problem since i bought this phone and android 4.4.4 did not solve the issue.
