DAC capability display

I have noticed that when I connect the Fiio Q3 dac/amp in my MacBook to listen with my headphones all 16/44,1 files outputs as 24/44,1 when I look at the DAC capability menu. This does not happen when I stream from Audirvana to my receiver without the Q3. Does anyone know what the issue is here?

That’s normal. According to Audirvana you’ll see the bit-width as reported by the USB interface when connected via USB. When you connect via UPnP to the receiver, you’ll see whatever the receiver reports.

Aah ok so there is no up-sampling being done?

Nope, that was also my concern when I started using Audirvana.

Ok that’s good to hear :+1:

But it’s strange because it’s only the 16/44,1 that outputs wrong, when I play 24/96 or 24/192 or even DSD files they come out as they should.

My DAC is 32bits, when i play 16/44 it shows 32/44, normal… playing 24/96 it shows 32/96 normal.
32 will always be on the right, like 24 for you since your dac is 24bits :slight_smile:

But my Fiio Q3 supports up to 32bit/768khz

maybe just the mac pro could not go to 32bits?

Hehe this was strange. I deactivated the Software volume control in Audirvana and now everything outputs correctly, 16/44,1 outputs 16/44,1​:smiley::man_shrugging:

That’s also not unusual. Some DACs behave like this.
