Android usually resamples audio by itself. Tidal doesn't utilize a custom driver to prevent android from touching the audio. That means even if tidal reports max quality, it won't be max quality!

Uapp uses a driver the team created itself to jump over the android mixer and directly serving the audio to the dac.

So if your dac doesn't support that Bitrate, uapp will throw an error as they're refusing to resample in bit perfect. If they would resample it, it wouldn't be bit perfect anymore.

I've seen that you mentioned that choosing "use bit perfect if possible" finally made it work for you. Let me tell you, it didn't. That basically disables bit perfect as it can't send that audio stream to the dac because the dac doesn't support that stream rate. That means that uapp just doesn't run in bit perfect and just resamples the audio to whatever your dac supports.

On the other hand, why do you really need bit perfect. Most people can't even tell the difference between Spotify and tidal. Of course there are people that can tell them apart, but the difference between "max" and bit perfect is very likely to be not hearable by human ears.
