[Bug]: Plexamp poor quality bluetooth audio on launch (macOS Big Sur)

I have a problem that might be related to this thread. I created a new one here, but I’ll also post in here in case this is related.

I’m using Plexamp 3.5.0 – macOS 11.4 – Macbook Pro mid-2015

Each time Plexamp is launched, it will change the sample rate of the audio device in use to its lowest supported rate. For example, when using the built-in output of the Macbook Pro, launching Plexamp will change the sample rate to 44100Hz, no matter what it was before.

I first noticed this bug when I had my Sony WH-1000XM3 Bluetooth headphones connected to the Macbook. After launching Plexamp, the headphones sample rate changed to their lowest supported rate, which is 16000Hz. As you can imagine, it was very noticeable…

But the problem isn’t just with my Bluetooth headphones, it seems to affect any audio device Plexamp is using at launch (like the built-in audio device of the Macbook, as mentioned above).

I’ve been experiencing this since the 3.5.0 update.
It wasn’t doing this before.

Edit:
Something occurred to me.

Is it possible that Plexamp isn’t actually changing the sample rate of the audio device to its lowest supported rate, but instead just tries at launch to always select 44100Hz (which would explain what I’m seeing with the built-in output of the Macbook)? And since the Sony WH-1000XM3 only two supported sample rates are 16000Hz and 48000Hz, Plexamp tries to set the headphones at 44100Hz, fails, and fallbacks to 16000Hz instead?

What is Plexamp trying to do with the audio device in use when it launches?
