Sample Rate Following on 3.7.0 not tracking after first track

I often play a playlist with various sample rates. Most LP-ripped songs are 192kHz. Many recently released songs are in 48kHz. 96kHz is common for classical music. Of course, the majority is 44.1kHz.

I play them with Roon at home because I have some dsf files, too.
Roon can switch sample rates quite smoothly. It’s hardly noticeable.

Is it that hard to switch rates without silence? I’m just curious.

By the way, I think switching rate is very important feature.
I can hear some noise when playing 44.1kHz songs with higher sample rate setting.
I guess that it’s upsampling noise.
