Hi,
I just finished re-loading Platinum into my new DAW. I keep getting this same message when I open Platinum and during a project session: "? AMD High Definition Audio Device-The above Audio/MIDI device was disconnected from your system"  Then it goes on to say "Would you like to reroute these outputs to an available device?  Clicking 'No' allows SONAR to remember output settings to this device."  I've clicked No, I've clicked Yes-just anything to get rid of this popping up again and again!  I'm using ASIO and RME FIREFACE 400.  Does anyone know where to go to eliminate this from popping up?
 
Thanks

Have you checked to see if the AMD HD device is selected in MIDI devices?

device-manager=disable it there
 
 
cheers

It sounds like your start-up template was saved with that audio device selected as the main input/output. Change your input/outputs on the start-up template and re-save it. I switched from an Edirol to a Behringer and my template kept popping up telling it couldn't find the Edirol.
 
 

If you are using an hdmi port as a secondary or more screen then that's where it comes from. - sometimes.
 
I get it when I turn on or off the TV I have connected to my synth rack PC as a second monitor. The TV audio hdmi output is like a sound card that gets disconnected / reconnected with tv power on / off sleep etc. So I make good an sure the tv is powered on first or at least at the same time as the synth rack pc so as to avoid this trouble.
