Can't change sample rates in Hi-Res output anymore.

Hi,

From past few months I'm unable to change actual sample rates in Hi-Res output mode. It was working fine before that. Now when i select any sample rate, the actual rate stays at 48khz. This issue started happening after i started using AutoEQ app called "Wavelet" that models sound signature to match my headphones. I had noticed before that this app can't process anything above or below 48khz, so naturally i won't use it with Poweramp when I'm gonna listen anything of Hi-Res.

 

Troubleshooting:

(a) So far i had tried uninstalling Wavelet app cause i had read somewhere on this forum that some audio apps may "hook" earlier into android's audio system than Poweramp does, so that Poweramp will lose the "authority" over the audio output.

(b) Wiped all caches from TWRP recovery.

(c) Uninstalled and reinstalled Poweramp.

 

My system:

Xiaomi Poco F1 running unrooted Arrow OS (Android 11)

Poweramp v939 from playstore.

@andrewilley That thread you shared with same issue as mine has not mentioned any solution to it.

I know that only root can change anything from inside the system, as i haven't flashed anything through TWRP.

Current i got two options on mind: dirty flash the same ROM or try Ainur Narsil audio mod.

@andrewilley As i said on the first post, everything was working fine on this ROM until i started using Wavelet app. And no, no way I'm gonna flash MiUi ever again.

Edit: I was testing other music apps and found that "Neutron" app is able to play at higher samples rates.

@andrewilley Any solutions yet?

I think this was the answer;

If you are going to reflash ROMs, you could try flashing back to a stock ROM and see if that works (which would be the only way we could easily support it anyway, Max's test devices only use stock ROMs).

In the past I have only seen the dev comment that support is for stock ROMs.

But the strange part from your first post is that this was working the way you expected prior to installing Wavelet. But now even after removing that app you cannot get Poweramp to go back to working as before. Either Wavelet has left you a nice present behind, or perhaps Poweramp actually wasn't working as expected and you didn't notice?

 

Perhaps this is the only other solution in the short term that you can try?

@MotleyGi had raided the internal storage to remove every single files/folders named Wavelet or it's package name, so i don't think any preset is in action (also I'm unrooted so wavelet won't be able to hide anything under root)

 

i had thoroughly tested every feature that i wanted in Poweramp before i installed wavelet & i can confirm that i was able to change the actual sample rate to anything i select.
