DIY USB Sound card, vol. II
Another attempt to make an USB sound card based on TI's PCM2704 chip by Miroslav Batek.
A successor to an older USB sound card - now with a new chip PCM2704 rather the PCM2702. The new one has built-in 5V and 3.3 voltage regulator, HID interface (MUTE, VOL+, VOL-) or S/PDIF output.
The schematic is almost copy of the datasheet circuit diagram, so the whole card is really simple and "easilly homebrewed".
