Hey guys,
 
I'm having some trouble with my ODAC. When I plug it in to certain computers or sources, it will work, and with others it refuses to output sound. See examples below:
 
Windows 7 Desktop (works with other DAC's over same USB port) --> USB Cable --> ODAC = "Windows doesn't recognize this device"
 
Windows 8 Laptop --> USB Cable --> ODAC = WORKS!
 
Samsung Galaxy S3 (Rooted, with with other DAC's) --> USB OTG Cable --> ODAC = Device not recognized by Linux
 
Modded Squeezebox Touch --> USB Cable --> ODAC = WORKS!
 
 
So what the heck is going on here? Is this a common issue? Is it just shoddy hardware?
 
If it is a problem on the board, I need to know ASAP so I can replace it.
 
 
PS: It makes a high pitched noise for a moment when it powers up, much like an old school camera flash would. Is this a problem?
 
 
Thanks!
