Just checked on my D30 Pro... it's the same. Just 32bit.

Thank you so much .
I am a little relieved that you are the same as me.
I received the following reply from the support team.

"This issue occurs because the UAC you are connected to only supports 32-bit, which is why it cannot be selected."


This is a bit odd since the D30 Pro's USB is supposed to 16-32 bit, but this seems to be normal.

Btw when I connect the Bluetooth adapter to the Ultra's USB it shows this. There seems to be no problem here.

 

[Burnside]

Interesting he got multiple choice in bit depth. Could it be ios has it and android don’t?

Same on iOS and Android for me - just shows 32 bit

This could be a problem if it’s just straight 32 bit. What if you’re playing 16/44? Will it play 32/44? Unlike with a choice of 16, 24 the dac can switch with either bit depth to make it bit perfect.

If you don’t select fixed resolution then it will be bit perfect

 

[Mr Ee]

What dac are you using? Is this iOS?

Currently fiio k11 r2r. Android only

Like I said, I'm not sure .
(My DAC does not display bit depth.)

 

[Saponetto]

Unfortunately I no longer have DACs with bitdepht limited to 24, that would be quite interesting to test...
the D30 Pro is the goldie oldie one here!

 

[Steve Woodhouse]

And you cannot drag it. That is strange.
Did you press the lines and then drag?

Yes.

 

[Ronnie D]

Yes.

Hi Steve, try pressing and holding on the middle of the preset not the bars. It should highlight the band just slide up or down. Ronnie

Cheers, I’ll give it a go.

For those having an issue with moving presets, try the following.
1. From the devices screen press the gear icon
2. Go to presets
3. Click on edit
4. Press and hold on the preset that you wish to move until it is highlighted and slide the selected bar to where you would like it moved to and release.
5. Hit done.
Hope this helps (and works) Ronnie

For now they are only selectable on my iPhone and not on Android...

But also for me they are not nice enough to use them.

That note was updated at some point, as it did not originally include that iOS part.

Yep. But now it's there.

Mine also is only 32 bit

 

[Maurizio]

I checked on my DAC. Although the only option is 32 bit, the DAC plays at 16 or 24 bits consistent with the album
