Playback speed randomly changes

Issue description:

Samsung Galaxy S9+ when playing back local media the files speed up and slow down randomly, but especially at the beginning of the files. It’s not particular files, It’s seemingly randomly occurring on all files. It’s very distracting and had to switch to a different player. I don’t know if this is a trial “feature” because I’ve seen another app that was supposed to change playback speed to try and force you to buy it.

Screenshot 1 shows a comparison of the playback from the phone on top vs. the source file.
Actually, I just had a thought, I think “remove silence” might be on, but then this is weird behaviour for it to remove silence from “inside” a file, at least silence shorter than say, 5-10 seconds. I get removing silence start and end, but this is faulty logic. But given the lack of empty space and the lack of pitch shift/time stretch on the signal itself, this is the only conclusion.

I don’t even see a remove silence option.

Seems ExoPlayer have issue with some of the data of those files.

And no there’s no limitations at all during the trial.

I believe I am having a similar issue. I put my player into debug mode and played part of a file where I heard it skipping/changing speed and uploaded the logs.

My device is also a Samsung S9. I will upload the file as well.

I uploaded it. The track is called I’ll Keep Coming.

Open your own issue with the proper details please.

I can’t reproduce on any of my devices I get the exact same result as playing on VLC on a computer and sound like your bottom graph.

Have you changed some settings? Enabled EQ? Or using external EQ? a DAC ?

Can you try to reset settings and play on phone speakers to see ?

All the EQ is turned off. The only thing turned on is replaygain. Resetting all options under playback to default has no change.
Otherwise it’s just default playing the app through the phone speakers/headphones/android auto

Then try to enable the EQ to ensure no other OS device EQ does something.

Do you have another device to test?

It would only be system EQ. But otherwise no, I don’t really have another device.
Enabling EQ makes no change.
I also have mp3 files it’s skipping too, so it’s not just wav.

The logs don’t show that you enabled it but just in case in now playing 3 dots verify that skip silence is not enabled ?

Yep, that was it. Thought I saw skip silence somewhere, that’s why I mentioned it at first. Which again leads back to why does it skip literally all silence instead of just start/end?

Because it’s written all ? :wink:

It’s for audio books not music.

Hmm. Well sometimes music a couple seconds of silence at the start and end, and other programs just skip that.
