Hi all, I have a T.C. Electronic Desktop Konnekt 6 external sound controller connected to my iMac (27" 3.4 i7, Mountain Lion) via Firewire. I use it as my only sound in/out. Looks like this: http://www.tcelectronic.com/desktopkonnekt6.asp When the iMac goes into sleep mode it stops power to the DK6 and when I wake the system there are loads of loud pops and cracks as the DK6 is re-powered. It's very annoying and probably damaging my speakers. Is there anyway I can still use sleep mode but not turn off power to my firewire audio device? Thanks.
