Nice work PA team. Good sound. Lean app. The audio quality has pulled me away from long-standing other player(s) usage, job well done.
I listen a fair amount over both wired- and bt- devices, more-so over bt though so I was very happy when the HQ audio worked over BT in addition to wired.
Only *quirk* I've experienced so far is two odd interactions with my car's head unit over BT.
1. PA starts playing on BT connect regardless of "resume" settings within PA
I don't know but speculate that the head unit is sending some kind of startup trigger that is causing PA to start playing but don't really know. I am aware that other audio players (e.g. RocketPlayer) have a tweak setting to 'ignore initial play command on connect' (or words to that effect) and I wonder if PA could use something similar.
The repro case goes like this:
PA idle (playback stopped or paused). Phone may be screen-locked or not, doesn't matter.
Start car, which fires up head unit and inities BT connection
Switch head unit to BT audio
No audio playback through car, however PA is *playing* - wake phone / unlock to verify
Attempting to start playback on car is unreliable, it may work and then pause at the end of the song, or just not work at all
Manually stop playback in PA
Play controls in car will now work as expected (play, stop, skip, etc.)
Flipping the PA "resume on connect..." settings does not appear help change the situation.
This odd behavior does not happen with the BT headset I have at my desk at work (LG HBS-730 "Tone") so I do believe it is something that the head unit is doing which is causing the behavior.
2. Head unit does not always update the progress-bar through the song as they play
The head unit progress meter counts up to 2 to 4 seconds of playback and stops.
I theorize this may be caused by VBR tracks w/o ID3 but have not confirmed, I need to run down a test case. If that is a known-cause of this behavior it would be good to know.
Thanks for your time and effort.
