I'm getting the same static @ 192 KHz with the UFX. When booting the UFX standalone, I get zero static @ 192, but when connecting the PC and starting playback of audio from Foobar 2000 @ 192 KHz, I get horrible static. Only in the headphone outputs. This continues until I reboot the UFX. When I have rebooted the interface I don't get static until I route audio from any input to the headphone outputs. They also seem independent from each other. When I route audio from SW playback 1 & 2 to Headphone 2 and not Headphone 1, I get static in only the HP 2 output.
I hope this makes sense.
I've not had this before updating to the 0.941 drivers, hardware revision 350 as it worked great a couple of weeks ago when I did the editing of this concert @ 192. I'm running Windows 7 Professional, x64, Core Quad Q6400, 4 GB ram.
I usually listen @ 96 KHz but today I did some 192 KHz listening to some choir recordings.
EDIT: I can't see the noise in the meters, either Pre or Post FX. It doesn't make any difference if I add EQ or not to the headphone output either. And the static has the same level, regardless of what volume I'm using. I'll try recording some of it.
EDIT2: http://www.livingsound.se/ufxstatic.zip It doesn't sound very nice at all. I used an insert cable from the headphone 1 out to the Analog 3-4 @ +4 dB. 24 bit 192 KHz unedited.
