Most probably a dumb question, but when I play a certain blu-ray I see in Audio Path:

Input 48kHz 32bit 6ch from source format dts
Output 48kHz 24bit 6ch using WASAPI (not using enough bits to output the input directly).

What does the last part of this mean ? Is my output sound somehow degraded and what can I do ?
As I said it is probably a dumb question but I am not so technical.

Normally you see this if the input file has more bits than your output (ie. 24-bit WAV file played with 16-bit output).

But if you're playing a lossy file (like AC3 / DTS from a movie), the text is misleading.  There's really no such thing as "bit-perfect" with a lossy file anyway.

Thanks Matt.
So this only means that my hardware isn't capable of playing 32 bit ?

Yes, exactly.

But since the 32-bits are from a lossy file (which doesn't really have a bitdepth, as explained at the link I posted), it doesn't matter.

Same question; different context.

Input:   96kHz 24 bit 2 ch from source format FLAC
Output: 96kHz 16 bit 2ch using ASIO (Not using enough bits to output input directly)

I'm outputting via USB to the ADL Esprit ADC/DAC which is supposed to support 24/96 via USB.

Any assistance will be deeply appreciated.

I'm outputting via USB to the ADL Esprit ADC/DAC which is supposed to support 24/96 via USB.

That means the ASIO driver is requesting 16-bit.  This is out of JRiver's control.

You might be able to configure the ASIO driver to change this (Options > Audio > Output mode settings > Driver control panel).

It's also possible there's a newer ASIO driver that uses 24 or 32-bit for input.
