pro tools could not initialize the focusrite usb asio

[NuBus]

Pro Tools 12.5.x
Focusrite Scarlett 18i8 Gen2
Latest Focusrite Control and Drivers

Win7


I've been running smooth but I'm now getting this error



"pro tools could not initialize the focusrite usb asio"


The Session opens fine But the error pops up when I hit play


It seems to happen on 48k Sessions But at times it will pop up on any sample rate session


A restert is needed after every time I get the error


Thanks for your time and Help

Do the latest Focusrite drivers support Windows 7? Ah you can't tell either.... how is anybody supposed to work out OS with is compatible with what?

What exact device are you using as the playback engine... is that the ASIO Focusrite device? Make sure you do not have ASIO4ALL installed/are accidentally trying to use that.

Is Windows sound or other apps trying to use the Focusrite device?... you need to set them to use a different device.

I went through all the settings with Focusrite Support



He Knew I was on Win 7 and didn't mention compatibility issues?


No ASIO4ALL Installed



I've ran Other Audio and Video apps with no issues



It still seems to come down to the few 48k sessions I open then everything is haywire!



Thanks for your input Darryl

Really double check that Windows sound and no other apps are trying to use that interface, that is very likely to be the cause here. Did Focusrite support work through that with you?

Lots of posts on DUC about that and related problems, e.g. http://duc.avid.com/showthread.php?t=389551

Hi Darryl


Thanks again for your feedback!!!!


In the Sound control Panel Playback devices and the Record Devices the 18i8 is disabled


The Speaker Icon on the tool Bar has an "X" In it



I checked the Link you sent and the original poster to the thread never said if his problem got fixed?


Strange how it is Just the 48k Sessions???

The normal reasons 48 kHz sessions fail is if some other software has the driver open at any other clock rate (usually 44.1 kHz) then trying to change to 48 kHz will fail. Same likely happens if you try 96 kHz. Does it?
