Hi folks,

I'm having an issue getting above 48k on my iMac 27 (mid2010) running Mountain Lion OSX. My Decware brand ZDAC-1 DAC has a Cirrus Logic CS4398 DSP which can do 192/24 bit but no aloha with USB - optical out works to 96/24 though but not in Integer mode running Audirvana 1.51. Anybody have a driver that can enable this or any suggestions ? Steve  said that DSP can be a little fussy, but didn't have a driver for it.

Thanks in advance,

Mike
