MAYA U5 supported sample rate

Developer: inrobert Views: 2251

Why MAYA U5 supports only 48 kHz sample rate while it uses VIA VT2021 audio codec and VIA VT1728A USB audio controller that both support 192 kHz / 24 bit?

How does it work? Is operating system feeding DAC with 48 kHz data or is it feeding with 192 kHz data and then it is resampled to 48 kHz? Could anyone give some details?

Hello.

The MAYA U5 is an USB 2.0 Full Speed interface.
It is designed as a maximum 24bit 48kHz 6ch due to the bandwidth limit.
Even if using the same VIA controller, the maximum specification is different depending on the number of channels.
When playing a music source with 44.1 / 48kHz on the MAYA U5, it's possible to use a bit-by-bit lossless digital output.
But when playing a music source with 96kHz or 192kHz, it is resampled according to the Windows mixer or Player.

It's not driver limitation.
We've said before It is designed as a maximum 24bit 48kHz 6ch due to the bandwidth limit.
The MAYA U5 with 5.1ch is used in many functions -recording, line-input, microphones etc.
In order to use all this functions, the bandwidth must have enough.
That's why, it need to resample the 48kHz to get the enough bandwidth.

I see.
So when I'm playing 2-channel signal it's not possible to pass 96 kHz data to MAYA, even though it would not exceed USB 2.0 capabilities? Is it driver limitation then?
