When using dSub in my car via Bluetooth, playback sometimes freezes at the start of a song. This happens about half of the time, and seems to be random. It is always during the first two seconds of a song.
I have experienced this issue with versions 4.5.6 and 4.5.8. I rolled back to version 4.5.5 and stopped having this problem. Just by looking at the changelog, I'm guessing the issue might be "Work around for Samsung's bluetooth metadata for 4.3+ devices"... maybe adding a toggle to disable this in the settings would help?
Phone: LG G2 D800 w/ stock rooted Kitkat 4.4.2
Car: Toyota Highlander 2012
Note - on all versions of dSub that I've tried, bluetooth metadata occasionally disappears on this car's radio. I don't know if that is relevant or not.
