HDX Crashes and endless fan spinning - Sample Rate Related

[aaronbrownsound]

I've been having a lot of issues with HDX on Windows. Support has been slow to respond after an initial call months ago so I thought I'd try the forums for user solutions. I've already reinstalled drivers, firmware, and done all forum troubleshooting so this is a bit of a hail mary post.

First, after installation the HDX card regularly lost connection and froze up the computer. After lots of hardware troubleshooting, and reinstallation as per instructions, it seems more related to my third point below and that HDX is only designed to work with PT and how PT relaunches for every sample rate change. It appears bad at quickly adapting to any sample rate adjustments.

Second, the fan spins full speed up and down every time I load a file in RX. For every file it takes about 3 second of fan spin to full speed, fan spin down, then repeating for every file. I have a feeling something in the HDX card requires spinning up and down the fan with every sample rate adjustment and RX seems to set that per file load. Never had this sort of issue with 5 other interfaces. Is there some way to disable this fan spin up or is it a hardware limitation?

Third, I've been trying to use it with Reaper and it isn't working well. If a Reaper session runs into any problems instead of just crashing my computer completely locks up, and the HDX fan spins at the highest speed possible. Everything becomes responsive until I physically turn off the Sonnet housing the HDX card. Then it comes back, but the HDX card isn't available as a device. My guess is that the HDX card locks up in this state and somehow pings the computer so much the drivers actually slow the computer to a halt. So sessions don't just crash, but require a full system reboot for the HDX card to return which creates a workflow that's unworkable.

Basically, it seems like HDX for Windows has far too many issues for game audio work where sample rates aren't consistent throughout the day. Anyone else run into such problems?

Greetings,

What version of Pro Tools are you currently running?
What version of Windows and what specs on your PC workstation?

More importantly, have you run DigiTest to check the integrity of the HDX Card(s)?

best,


Jeff

Hi,
The thing is most of the issues are with other software. Izotope RX fan issue appears to be with how the HDX forces it to spin up fans while it's being initialized or sample rates change. Thus every start up gets 3 full fan cycles for 8 seconds and 2 seconds everytime I do anything. It think it's also when the fan issues occur with Reaper when it crashes. The HDX seems to get stuck in the fan cycle in that moment so instead of the quick crash it freezes up the machine trying to find the correct sample rate and such. Fine when Reaper doesn't crash, but if it crashes or hangs the system locks up.

The HDX card works pretty well with just PT, but is very rough for Reaper and RX work so I end up bypassing it when not in PT. In general, I'm avoiding using HDX due to all these issues.

PT 2024.10.2 ultimate.
Windows 11

Many Digitests have run and the card checks out fine.
