saw the led flashing. after opening the app this childish rocket appeared. what is new and i could start immediately. so accomplished fact. but no problem. as long as qobuz works it is all good.

I got it too ... sadly the covers in the usb media library still looks pixelated. Doesn't matter which resolution I upload.
Edit: only in the smaller cover view - when full screen it looks fine now. Must be something with the scaling ... but for sure not that important.

@hgo58 do you also feel the 0dB full-scale approaching?

Unfortunately the VU meter is still a power amplifier meter and although it may be more precise (whatever that mean here?) I cannot see where the 0 dBFS is (digital clipping).

@hgo58 Just got this update too... meh
Well, at least that absurd, weird needle randomly bumping-to-full-scale when turning the volume knob went away.

is it normal that after a firmware updates all services in the browser section are set to active? no big deal. but wasting at least five seconds of life time

@Machiavelli Just checked.
My device still shows what was enabled before the update.
Almost curious.

No, that should not happen unless it was a factory reset.

Mine updated without changing any configurations.

I would take either option right now as it is a lot of clicks to change it every time.

You can also slide the VU meter in on the Ultra screen.
