Chord Mojo Settings

Hi,
I am retired & a bit long in the tooth for new highly technical info. I have a Chord Mojo Dac which to my ears already sounds great. However i am aware there are settings in Audirvana for each DAC such as “use large Wasapi i/o buffer” that is meaningless to me. Is there any one who could recommend the general settings I should apply.
Many thanks,
Mel Fisher

Hello @Mel_Fisher,

Can you send me a copy of the “Debug Info” after selecting your Chord in Audirvana? You can get it in Audirvana Settings>General>Debug Info

Note: By clicking on the Debug Info button, Audirvana automatically copies all its content, all you have to do is paste it in response to this message

Set it to Non MQA. It’s not MQA capable device.

Hi Damien,

Followed your instructions & sent the debug info. Someone called Bitracer commented that the DAC is non MQA.

I am not sure if this is a member responding or an official Audirvana response to all the various settings.

I look forward to hearing from you soon.

That’s true, no Chord dacs are MQA compatibile
and there is no mention of MQA in the specs https://chordelectronics.co.uk/product/mojo/

Hello @Mel_Fisher,

The Mojo is not MQA capable so you can set it as non MQA in Audirvana. Have you installed the Windows 10 driver for your DAC? https://chordmojo.com/support/#driver

If it’s the case, can you look at the audio output menu and click on ASIO? Do you see a source you can select?

WASAPI.ASIO

For the other settings you can try to enable upsampling with power of 2 as setting to get the best of your DAC.
