that is made by unknown company and sold under several brands (just search for
"USB 5.1 AUDIO ADAPTER" or "AC1500 USB" in Google).
It works (stereo playback/recording only, 5.1 sound does not).
Cheap (around $17 in Moscow).
Has LEDs that blink when data is sent over USB bus.
You have to find correct recording volume, otherwise all you will get
is a cheap guitar overdrive - it seems that 100% rec gain is realy 200-400% gain over
source level. If I set a mixer (Behringer MX) to -10db (level required by most
consumer equipment) and line volume at 100% I'm getting
distorted sound under any OS (both 7-CURRENT at home and XP at work).
I will not recommend it to anything serious.
