Steps to reproduce

1. Play an audiobook and wait for the sleep timer to count down.
2. When the volume starts to lower, shake the phone to reset the timer.
3. Observe that the book continues playing at reduced volume.

Expected behaviour

• The volume should be restored when the phone is shaken to reset the timer

Actual behaviour

• The volume is not restored, and the audiobook continues playing at reduced volume

I have noticed that if I manually increase the volume using my phone's volume slider to compensate for the partially faded volume, the next time the sleep timer starts to fade, it first goes back to full volume and then fades from there.

I'm not able to reproduce this.

I set the sleep timer to 1 minute then with around 10 seconds remaining I shake the phone. The volume resets properly.

Can you reproduce this every time? Are you using chromecast?

Interesting...

Test 1:
1min timer.
Watched it count down.
Noticed the sound lowering with about 20s remaining.
Shook the phone at 10s remaining and observed the timer reset & volume went back up.

Test 2:
1min timer.
Started playback, then turned screen off.
Using timer on laptop, observed sound lowering around 20s remaining.
Shook the phone at about 10s remaining and observed volume went back up.

Test 3:
5min timer.
Started playback, then turned screen off.
Using timer on laptop, observed sound lowering around 30s remaining.
Shook the phone at about 10s remaining and observed playback continuing at reduced volume.
Turned phone back on, observed timer reset to 5min.
Pressed pause/play & observed playback back at full volume.

Seems like the sleep duration somehow impacts whether the volume is restored.

Further to my last: turned off restricting battery usage for the app & it restores volume when shaken.

[advplyr]

Thanks for testing. The battery optimization on some devices is closing background processes and causing some strange results. I think we'll have to put an alert in the app about this. There is a feature request for that already.

I still have battery optimisation turned off for abs but last night experienced the same thing with the volume not restoring. Even if it is a battery optimisation thing, can't that be worked around? I have used Smart Audiobook Player for many years & it rests the volume without having to disable battery optimisation.

[advplyr]

If it happened with battery optimization turned off then it is not battery optimization. I haven't reproduced this and can't think of how this would be possible

[YodaDaCoda]

Yeah I thought it was odd. Is there any additional testing I can do?

I'm on android 12 Samsung S10e OneUI 4.1 Same symptoms as YodaDaCoda, 100% reproduceable.

I use a 15 min sleep timer. Hitting pause and then play will restore the volume.

If instead of pause/play, I increase volume to compensate, then next time the timer starts to expire, the volume suddenly gets very loud, then starts to fade.

Turning off battery optimization did not help. (I set battery to "Unrestricted" for this app)

[advplyr]

Thanks all for the testing. I did end up reproducing this and it will be fixed in the next release

Fixed in v0.9.64-beta
