I have issue with Dragonfly Cobalt DAC

Hi!

I tried to Audirvana yesterday and found out a lot of things changed from last access.

Anyway, I have purchased Dragonfly Cobalt and tried to play with Tidal.

It’s not working with my MacBook Air (M2) and showed ‘integer mode’ problem.
When I disconnect Dragonfly Dac, Tidal plays with MacBook Air internal speakers.
and with Dragonfly inserted, turned off ‘integer mode’, there’s no sound.

Please show me the way to solve the problem.

Here’s the Debug info.

Do you use an external hub or an adapter to connect the Dragonfly?

Also reduce the pre-load cache to 4000MB.

I have connected with dragonfly original USB C to USB A converter.

I tried but in vain.

Hi @danden,

Can you send your debug info while you selected your Dragonfly in Audirvāna?
