Steps:

1- Play some music through the phone speaker
2- Connect to bluetooth headphones and play some music
3- Disconnect from headphones by turning off the bluetooth headphones
4- Play some music through the phone speaker

Expected:

Music plays, at the same (or similar) volume to step 1.

Actual:

All audio is very quiet, or possibly muted, and it's impossible to turn it back up again without restarting b2g.


This is a regression, this feature worked fine at some point a month or two ago, but it took me a while to realise this was happening, and to pin down exactly what was happening.

This is reasonably serious, as it seems to also affect ringer volume (but not in-call volume, as far as I can tell).

If I get the time/remember, I'll test to see if this happens in 2.1.

ni? Star to check from audio part first, this looks like not related to bluetooth, but audio volume settings.

It seems not to disconnect the A2DP.

QA-Wanted for a branch check first, then we'll look at adding back the regression-window

The bug repros on Flame 2.2 and Flame 2.1
Actual result:  After turning off the Bluetooth headset, sound cannot be played through the device when the song is resumed.  I also noticed that the timer on the song accelerated when it was resumed.

Triage: regression, blocking.

Adding blocker as the culprit is clear from the regression window in comment #8.

In my thinking, it could be same as bug 1072021. I'm checking it

After did some experiments, I found when problem is happening, ProcessDelayedA2dpRoute bt address is empty. This problem is the same as bug 1072021.
