Audio card with built-in ground isolator?
- by Dave Jarvis
What audio cards would you recommend that eliminate hum, and hard-drive & mouse movement signal interference?
Hardware components:
Motherboard. Asus P5Q SE
Audio. Realtek ALC 1200, 8-Channel High-Definition Audio CODEC (on board)
Harddrive. WD Caviar 320 GB
Mouse. Logitech Marbleman USB
Mixer. Mackie d.4 Pro
Amplifier. Sonance Sonamp 260
All components are plugged into the same Monster Power HDP 910 powerbar (does not help eliminate noise). I have no other components plugged in. The computer uses a Monster iCable 1000 to go from mini (on board audio) to RCA (mixer). I have moved the cable as far from other cables as possible.
A ground loop isolator between the mixer and on board audio eliminates all noise.
I would rather not use a ground loop isolator; an internal audio card that is Linux-compatible (Kubuntu) would be ideal.
Suggestions?
