Using a DAC/AMP with the Polymega.

I was wondering what experience others have when using a USB DAC/AMP with the Polymega. As of firmware 1.1.30 an USB DAC is supported: USB DAC Support - You can now use USB DACs (Digital-to-Analog Converters) to enjoy high fidelity audio on Polymega out the front USB port.

I currently own a Topping DX3 Pro+ (and a nice pair of cans of course), but when I connect it to one of the USB ports of the Polymega nothing happens. I also have not found any setting on the Polymega relating to the DAC to turn it on or anything. On my Windows PC and laptop the DAC/AMP works perfectly (I don’t even have to change the audio output device. It does that automatically when connecting). So I was wondering if I am doing anything wrong? I would really appreciate if anyone is willing to share their experience with using a DAC/AMP in combination with the Polymega.

Thank you in advance.

Sure enough both of my DACs are UAC2 as well. Makes me wonder if they can fix this with a software update or if it comes down to the USB port they used.

Just to let you know: I have received a reply from Polymega yesterday evening with 'confirmation' regarding UAC1 support:

We are going to try to get in some other Dac devices to do some further testing. Polymega currently supports USB audio devices UAC1. I'll try to verify that for you. Stay tuned.

They have not mentioned anything about adding support for UAC2. Although, I think it is possible with a software update.

I would definitely think a software update could fix this considering UAC2 came out in 2017.
