i have recently purchased a new R2R -2 DAC, from audio-gd. http://www.audio-gd.com/R2R/R2R2/R2R2EN.htm
The OS recognizes the dac but can only play sound upto a minute, thereafter it goes mute and doesn't play at all. The usb module of the dac is [font]Amanero combo 384.[/font]
Any help is appreciated.
