Hoping someone has an idea of what is going on and what to try to fix it.

Yesterday I switched the 828es to ADAT mode to use with my RME Babyface Pro FS. It was also working fine and I was able to route audio in/out.

I tried to switch it back to audio interface mode and it showed up as a selectable interface in my DAW options. However, it appears I can't set the block size (tested in a few DAWs). I can't get any audio when in interface mode. I get no audio playback in the DAW, or from any other source (Foobar, Youtube etc.)

I flashed the latest firmware again via USB. Tried a factory reset. Uninstall/install. Removed it via Device Manager. Tried older driver. Tried different USB cables. Updated BIOS. Repaired Windows. Disabled firewall. Everything seems to connect to the MOTU just fine, I can access the mixer page, change the sample rate, view it as a device in Windows sound prefs and it's showing in Device Manager without issues.

I plugged it into my other PC and it works fine immediately after installing the driver. My RME Babyface is working fine as well on the PC that the MOTU stopped working on.

Any ideas?
