My Volla 22 has now received version 13 (Halium 13?). However, I would now like to replace the Volla OS with Ubuntu Touch. Will this work with the Volla/Android version 13? Or how can I reset the phone to Volla OS 12? Factory reset didn't work. According to the instructions, Halium 12 is required for installation.

Just a few basic thoughts from me:
Many mobile OS have disappeared because there simply wasn't much choice in apps. UT also doesn't have a wide distribution because there aren't many apps available. My wife would never switch from Android to UT for this reason. She simply lacks the little "helpers".
Therefore, it is important that every app, no matter how small, should be gratefully accepted. Every developer should be encouraged to continue to work for the community in his spare time (thanks to arubislander). His intentions should not be questioned. It doesn't have to be the huge "you-can-do-anything" app. Even the smallest app strengthens the OS. That's the only way UT can become something big.

@arubislander Thank you for your suggestion.
I would have thought there was a simple solution, such as uploading a stock rom to the device via adb.
My problem is that I bought the smartphone second-hand and I don't have an invoice for it. Maybe Volla support can help me anyway.

@sven After the factory reset, the smartphone remains in Volla OS 13, i.e. Halium 13. There is no chance that I can get it to Volla OS 12 with on-board tools.

@klh Yes, you are right.
Testing on my app revealed that the screen must kept on to activate the sleep timer. This is unacceptable.

But the WIP of Music Player / Sleep timer shows no activity since 2 years and the trial version with the fix is outdated.

@klh said in Python should reset PulseAudio:

@digi6622 I don't see any feature requests about what you describe here: https://gitlab.com/ubports/development/core/mediaplayer-app/-/issues
Where was the request made if nobody responded to it?

You can find requests here:

@arubislander
Thanks again !!!
It sounds very simple. Actually, I had assumed that the sound outputs (media-hub and playing a wav-file) were on different sound slots and thus did not affect each other. Therefore I did not think in this direction at all. But I give it a try. Thanks a lot.

I would like to reiterate that, as a proof of concept and by way of exercise, this is all very well. But a proper sleep functionality should be either implemented in the OS somewhere, as a global feature (maybe in settings?), or in the Music app itself as a local feature.

I understand your concerns. Neverteheless I would like to offer my app in the OpenStore, because some members here in the forum (including me) wish this app. The maintainers of UT and MediaPlayer did not respond to this request.

@arubislander
QML and Javascript are okay.

@arubislander said in Python should reset PulseAudio:

@digi6622 and is using Python a hard requirement?

It would be nice if possible. I'm not fit in C++ or other codings.

@arubislander

Maybe slide I to my DM's to talk it through?

That would be really nice !
In short words what my app should do:

• Select a certain number of minutes (it already works)

• Go to sleep for the number of minutes (works too)

• After this time the app close media-hub or decrease volume of this soundchannel or mute pulseaudio (= my problem)
