Lesso Posted February 7 Share Posted February 7 (edited) Hello Poweramp forum, I'm having a problem with Poweramp. Whenever I reconnect to bluetooth output the audio keeps stuttering which is caused by a rapid pause / unpause coming from processed commands. So basically the steps to reproduce are: - connect phone to bluetooth output (headphones, speakers, etc) - start playing music In the "Last processed commands" section this problem looks like this: Spoiler ================== 08:26:25.314 PlayerService reloadPipeline allowPlaying=true forceResume=false state after reload=2 ================== 08:26:26.345 PlayerService reloadPipeline allowPlaying=true forceResume=false state after reload=2 ================== 08:26:26.984 PlayerService reloadPipeline allowPlaying=true forceResume=false state after reload=2 ================== 08:26:27.989 PlayerService reloadPipeline allowPlaying=true forceResume=false state after reload=2 ================== 08:26:28.621 PlayerService reloadPipeline allowPlaying=true forceResume=false state after reload=2 ================== 08:26:29.644 PlayerService reloadPipeline allowPlaying=true forceResume=false state after reload=2 ================== 08:26:30.282 PlayerService reloadPipeline allowPlaying=true forceResume=false state after reload=2 ================== 08:26:31.342 PlayerService reloadPipeline allowPlaying=true forceResume=false state after reload=2 ================== 08:26:31.984 PlayerService reloadPipeline allowPlaying=true forceResume=false state after reload=2 ================== 08:26:33.019 PlayerService reloadPipeline allowPlaying=true forceResume=false state after reload=2 ================== 08:26:33.653 PlayerService reloadPipeline allowPlaying=true forceResume=false state after reload=2 ================== 08:26:34.669 PlayerService reloadPipeline allowPlaying=true forceResume=false state after reload=2 ================== 08:26:35.305 PlayerService reloadPipeline allowPlaying=true forceResume=false state after reload=2 ================== 08:26:36.347 PlayerService reloadPipeline allowPlaying=true forceResume=false state after reload=2 ================== 08:26:36.983 PlayerService reloadPipeline allowPlaying=true forceResume=false state after reload=2 ================== 08:26:37.994 PlayerService reloadPipeline allowPlaying=true forceResume=false state after reload=2 ================== 08:26:38.630 PlayerService reloadPipeline allowPlaying=true forceResume=false state after reload=2 ================== 08:26:39.684 PlayerService reloadPipeline allowPlaying=true forceResume=false state after reload=2 ================== 08:26:40.321 PlayerService reloadPipeline allowPlaying=true forceResume=false state after reload=2 ================== 08:26:41.390 PlayerService reloadPipeline allowPlaying=true forceResume=false state after reload=2 ================== 08:26:42.023 PlayerService reloadPipeline allowPlaying=true forceResume=false state after reload=2 ================== 08:26:43.057 PlayerService reloadPipeline allowPlaying=true forceResume=false state after reload=2 ================== 08:26:43.689 PlayerService reloadPipeline allowPlaying=true forceResume=false state after reload=2 ================== 08:26:44.730 PlayerService reloadPipeline allowPlaying=true forceResume=false state after reload=2 ================== 08:26:45.367 PlayerService reloadPipeline allowPlaying=true forceResume=false state after reload=2 ================== 08:26:46.389 PlayerService reloadPipeline allowPlaying=true forceResume=false state after reload=2 ================== 08:26:47.025 PlayerService reloadPipeline allowPlaying=true forceResume=false state after reload=2 ================== 08:26:48.049 PlayerService reloadPipeline allowPlaying=true forceResume=false state after reload=2 ================== 08:26:48.686 PlayerService reloadPipeline allowPlaying=true forceResume=false state after reload=2 As you can see, the commands are coming in very rapidly and it results in an annoying stutter. What I tried (without success): different bluetooth headsets disable / enable "Resume On Bluetooth" disable / enable OpenSL ES Output enable unrestricted battery usage for PA What helps temporarly: stop the playback in Poweramp and wait for about 30 seconds --> for some reason this solves the problem until the next time I disconnect + reconnect my bluetooth output Here is more information: PA build: 971-976 (happens on older builds too though) Phone: Sony Xperia 1V Android: 14 (kernel 5.15.94) I could also imagine that there is some sort of problem with the deep integration of music playback functionality in Sony phones? There is a preinstalled Music app (from Sony) which hosts a couple of settings. Additionally there is the (optional) Sony Headphones App which also does provide various settings. I tried forcefully stopping the Headphones App and even completely disabling the Music app, which didn't help. I would be really happy if I could get some help with this as I really like Poweramp and I really like my phone but apparently they don't work together.

andrewilley Posted February 7 Share Posted February 7 As you say, there's a lot of activity after connection, either from the headset, from Android, or from Sony's installed software. There is a feature in the latest Poweramp builds (currently 981, available from the Downloads tab above) to ignore Bluetooth remote commands for up to the first 10 seconds of a Bluetooth connection, which might be worth trying. I'm not sure if that is limited to ignoring only button-simulating events though - e.g. KEYCODE_MEDIA_PLAY_PAUSE ACTION_DOWN and KEYCODE_MEDIA_PLAY_PAUSE ACTION_UP - which are not occurring in your log.

Solution Lesso Posted February 7 Author Solution Share Posted February 7 Hey @andrewilley thanks for the fast response. I did some more investigating because I really want to make this work. I discovered this reddit post which indicates that there are several problems on the mentioned Sony Xperia phones including bluetooth connection issues and issues with the AptX implementation. Now it's just speculation that this is actually related but it lead me to trying out different PA output settings after installing your suggested build (981). So as said I mainly did two things: - install PA 981 and set "ignore last processed commands" to 10 seconds - change output from OpenSL ES to the experimental Hi-Res Output (under Output Plugins) and apparently now the problem is gone. I'm pretty certain that it isn't the "ignore last processed commands" setting that did it, because I can also not see the "PlayerService reloadPipeline" command spam any more at all. It just stopped happening for some reason. That being said, I don't want to assume that the problem is resolved fully after just a few minutes of being gone. I will report back in about a week or two (or earlier if the problem reoccurs). Let's hope for the best. Link to comment Share on other sites More sharing options...
andrewilley Posted February 7 Share Posted February 7 AAudio is another good Output method to try, which does support some hi-res options. But the Experimental Hi-Res mode avoids a lot of Android audio processing, so that might be what is fixing your problem. Andre Link to comment Share on other sites More sharing options...
maxmp Posted February 7 Share Posted February 7 @Lesso the changing output may also change default buffer settings, so may be slightly added buffering for the Open SL will do as well (if ever needed). Link to comment Share on other sites More sharing options...
Lesso Posted February 7 Author Share Posted February 7 (edited) Okay, thanks for the input. I will try out different settings. Is there any inherent advantage of AAudio or OpenSL? I'm asking because I don't see a reason to switch back to these if the experimental Hi-Res works for me. So far I can also not make out any audio quality loss.

andrewilley Posted February 7 Share Posted February 7 If it's working for you, and you are happy with the sound, don't mess. Andre Link to comment Share on other sites More sharing options...
Lesso Posted February 15 Author Share Posted February 15 (edited) Just some feedback after about a week: I tried AAudio and OpenSL with increased buffer size but both immediately recreate the original problem. With experimental Hi-Res it stays gone, which is why I marked my own reply as the solution. The only downside so far is that the overall volume seems to be lower compared to other outputs. When I set the volume to about 50% I used to consider it to be fairly loud already. Now 50% is where I start to hear output. The overall maximum volume is lower as well, but not drastically. The volume steps are not really linear anymore. It feels like an exponential curve. It's not a big deal though. Thanks again for all the support.

andrewilley Posted February 15 Share Posted February 15 Do you have DVC enabled for your Hi-Res output? That often gives slightly higher volume levels. Andre Link to comment Share on other sites More sharing options...
Lesso Posted February 15 Author Share Posted February 15 I didn't disable it if that's what you mean. There is a setting that says: "No DVC" and it's turned off, so I assume DVC is enabled. Link to comment Share on other sites More sharing options...
andrewilley Posted February 15 Share Posted February 15 Yes, that sounds OK. You'd see it mentioned in the Audio Info display during playback too. Andre Link to comment Share on other sites More sharing options...
