HDX can't find Lynx Aurora 8 LT-HD

[hugoleitao]

Hi

I just swapped my Avid Native to a HDX, everything was working great on a 2009 5.1 Mac pro 6 core 3.46ghz with latest version of PT, 2021.3.0.

After install the HDX card Pro Tools show a message saying it can't find the audio interface connected to the HDX.
Already installed the HD Driver, Pro Tools, reset the PRam but nothing seems to work.
Same machine I was using with my native card, digilink license is ok, and the Aurora firmware shows 28.

Anyone has a clue for what's going on?

Power to card?
HDX firmware ask after install?
Reboot and run digitest?

I'm still waiting for my power cable, but I was told that I should be able to see the HDX without cable, I was definitely not planning to use the card without the power cable, do you think could be that? Because the HDX is recognised by Pro Tools as you can see by the screenshots.

Strangely and unlike my Native it didn't ask to update the firmware.

Digest won't open and gives me the -1175 error

Power needed. Although you selected HDX engine, it sees no voices.
Never used or tried without power connected.
Your other question will be power source.
What is you video card? 6, 8 or dual 6 pin?

Hey, thanks for your feedback

Yeah the power is another problem since I don't have any more psu's available. My Mac Pro came with a nVidia GTX 680 2GB, I believe is dual. I attached a pic.

I figured out the easiest way to free at least one psu is getting a video card that doesn't need power, a MSI 560 RX seems the right candidate, is there any Y cable that could provide enough power for the video card and HDX?
