Strange EQ Behaviour

Issue description:

Moved to Symfonium, tried to set up my EQ on my Motorola Edge 50 Pro.

I play my music over BT using my FiiO UTWS5 earhooks with DZ4 headphones. When I set up AutoEQ or any other effect, I get no result or change in audio. I can roll my preamp to -15, and it does nothing. However, when digging around, I found that disabling “Prefer internal decoder” seems to temporarily resolve the issue. I say temporarily because as soon as I manually change tracks, or as soon as the next track plays, the EQ stops working again, and this time turning it on fixes it. I’ve tried to make sure that Wavelet is off, that the system equalizer is disabled, and that Dolby Atmos from Motorola is silent too. Nothing seems to help. Even flicking EQ on and off doesn’t do anything; just flicking the decode settings seems to do anything at all.

Source files are universally in FLAC.

Additional information:

 
It appears that the setting being on or off has little or no bearing on the issue itself, as the EQ can work with both the setting on and off, it just needs to be changed while a song is playing for the EQ to work.
 

Reproduction steps:

 

  1. Play music, EQ enabled

  2. EQ doesn’t affect output in any way, shape, or form.

  3. Enable/Disable the “Prefer internal decoder” option.

  4. EQ becomes responsive again

  5. Manually skip or listen to the whole track

  6. EQ becomes ineffective again

  7. Disable/enable “Prefer internal decoder” to have EQ effective again.

Some devices have broken implementation of those libraries, check uncheck the option just restart the player to get a new session ID that probably force reset their internals.
Nothing I can do about those, but I’ll add a custom EQ that does not rely on those libraries in a future release.
