I got a problem when playing music after the screen is turned off. When on BATTERY, the music is interrupted. After couple of seconds it's playing again and it's again interrupted. When the screen is turned on (still locked) the music is playing without problem. When on BATTERY and Wi-Fi is turned off, it's playing without problem. When on USB it's playing without problem regardless of Wi-Fi state. It's not only about music player. When I receive a message it vibrates but it plays sound after the screen is activated. Incoming call is without problem. Clean reinstalling via UBports installer didn't solve it. Can someone confirm it? Maybe it's caused by some of recent updates.

I can confirm "When on BATTERY, the music is interrupted. After couple of seconds it's playing again and it's again interrupted. When the screen is turned on (still locked) the music is playing without problem. When on BATTERY and Wi-Fi is turned off, it's playing without problem." and "When I receive a message it vibrates but it plays sound after the screen is activated. Incoming call is without problem."

I have not tested more. And: no problem with the Apps: "Flas" and "Clound Music" .

@c4pp4 @eichenbast how are you playing the music?

This is probably caused by the media-hub not keeping/aquiring a 'wakelock'.
Flas probably works since it plays a stream (which is 1 track) for which the lock is acquired. (I don't know what Cloud Music is.)

When charging or with screen on the phone does not go in sleep mode so the music plays fine. Some app or service preventing to go to sleep (for example by having a lock) also keeps the music playing fine.

@wdehoog said in Sony Xperia X (suzu/F5121 & F5122):

how are you playing the music?

I'm using preinstalled UBports Music app.

wdehoog · 15 Jun 2020, 12:57

@c4pp4 Then I would expect the first track to be played ok (media-hub has the lock) and the next ones being 'interrupted' (media-hub) does not acquire a new lock for the next tracks).

If I remember well you can see the locks being aquired/released in /var/log/repowerd.log.
Something like requestSysState and clearSysState. Maybe it is worth checking to see if this is the issue.

No, it's interrupted immediately after the screen is turned off.

/var/log/repowerd.log

OK, I'll check it.

c4pp4 · 15 Jun 2020, 16:41

Please, where can I find changes applied via System Settings > Updates named "Ubuntu touch" with number e.g. 335, 336 etc.?

wdehoog · 15 Jun 2020, 17:23

@c4pp4 Is the Music app still in your list of apps that will not be suspended (marked 'prevent app suspension' in UTT)?

or use: gsettings get com.canonical.qtmir lifecycle-exempt-appids

Yes it is. I don't think it's related to suspension. It looks like there is a very agressive powersave management or something like that. The Music app is active, but it plays about one second and then it's interrupted and after a while it plays and it's interrupted again. The same is SMS notification, it vibrates immediately but the sound notification is delayed. And now I find out it's related to the sound of incoming call, the same as SMS, it vibrates, but the melody is delayed and then played and interrupted as the Music player.

wdehoog · 15 Jun 2020, 18:47

@c4pp4 still strange that some other apps can play without being interrupted. anything interesting in log files? /var/log/syslog or /var/log/repowerd.log or ~/.cache/upstart/media-hub.log

I'll check it later if you don't mind.

@wdehoog
Maybe the problem is caused by this commit https://github.com/ubports/repowerd/commit/cfb1cec49ab53a33458112b7aa1ae61afba8e207

I've compared /var/log/repowerd.log when Wi-Fi ON (music is interrupted) and OFF (music plays) and there are additional lines when Wi-Fi is ON:

@c4pp4 If the problems are caused by the repowerd commit you refer to then it remains strange that some apps do not suffer from this issue. The relation to wifi is also a mystery to me. I am afraid I cannot be of much help here.

eichenbast · 16 Jun 2020, 08:49

@wdehoog I am not sure, that for example "Flas" is not related. Cause I noticed, that after a while it also stops. First I thought, it is because of the quality of My wifi connection .

wdehoog · 16 Jun 2020, 20:15

anyway after updating now I have the exact same problem on my opo. boehoe....

c4pp4 · 17 Jun 2020, 11:01

@wdehoog
what is the update number in your case?

BTW: The problem is not caused by the commit. I've tried repowerd without it.

malditobastardo · 17 Jun 2020, 16:53

@c4pp4 Any chance to go back to stable? Or to a previous image without this issue?

wdehoog · 17 Jun 2020, 19:09

@c4pp4 I notice lots of logs in repowerd.log, lightdm.log and syslog. top shows lots of activity for systemd-logind and polkitd and sometimes Networkmanager.

still no idea what is going on.

since this is no sony-xperia-x specific problem we better continue somewhere else. a github issue?

c4pp4 · 17 Jun 2020, 19:18

@malditobastardo
I'd like to try a previous image too but I'm not sure how, maybe @fredldotme can help with it. I just compiled custom repowerd package to exclude the problem is not caused by the commit.

@wdehoog
Maybe the problem is really media-hub and turning the wifi off just starts a network dbus service using wakelock and then the music is playing without interruptions or something like that.

c4pp4 · 25 Jun 2020, 18:59

@wdehoog Should be fixed, it was the commit
