I don't load any drivers for the Chinese knockoff for use under X64. I can list the drivers used by the card if you wish. It shows up as generic USB Audio. I have a HP8903 if real test specs are needed, at least at the 16 bit level. [I trust test instruments, not programs.] I can view the residual on a DSA as well if needed. The knockoff uses a CM106-F+/L+. [The L+ I believe, but I would have to open the box.] Specs for the DAC are listed as typical. http://www.ic-on-line.cn/IOL/viewpdf/CM106-L_1102282.htm The chip specs are pretty poor, but you can do much worse in real life. Of course, none of this gets the card going on my Suse linux box. I'm going to investigate live CDs of other distributions to see if the problem is peculiar to Suse. I posted a list of the modules Suse uses to the list. The Chinese knockoff and the Griffin iMIc show up under Alsamixer just fine, but don't work in any programs.
