I have a SubZero SZ-08USB mixer connected to my laptop, and trying to record three separate audio tracks.
I downloaded a driver: SubZero SZ-AI2 2x2 USB Audio Interface Driver & Control Panel
However, when I go into preferences: devices: recording - it only comes up with mono or stereo, and not the 4 tracks you would expect to see.
I should add that the mixer device is visible in Audacity.
I spoke to someone from Gear4Music (who I bought the equipment from) on the phone and they said I have set everything up correctly, but sounded like a computer/driver issue.
Any advice would be greatly appreciated!
