No (practically) for the NFB-12
Yes for NFB-2, NFB-3, NFB-5, FUN, NFB-10, NFB-19
Ok so right from the man Kingwa :
"The DA chips we had applied all with 32 bit input, we have do some lot test and compare , consider the 32bit is better match, so in the 2014 driver have force on 32 bit.
Still unsure why, but I'll take his word for it.
Google how to prevent windows from auto-restarting during a bsod and you can see it the next time it happens. I've had mine bsod once and the source was the via driver.
I have send an e-mail to Kingwa. I hope the link will be available again soon.
Edit: I received a mail from Kingwa with a new link. (Good service as always.)
Some one use 'internal usb module' for another device? On old tennor i see http://www.audio-gd.com/Pro/dac/TE8802/TE8802kitEN.htm SP/DIF exit, but on via 32 may be not?
