Since I got the RTX 3070 my Audigy 5/RX headphone output received the coil whine from the video card. I tried multiple solutions with external power supply for audio card but none removed 100% the noise received from video card. So after many tries i considered repurposing the old Audigy external bay and since the new motherboard didnt have any PCI slots or drivers for SB0320 don't work with windows 11...
Target for today:
After opening the box and powering up the board all essential components work without I2S bus to the PCI card.
What i needed to use it's only 3 chips.
SPDIF to I2S - CS84154A
I2S to Analog DAC - CS4392kz
OP-AMP - 4556a
And a jumper wire from TOSLINK RX diode to SPDIF input
The unit it's powered from 12V line and I wanted to use USB for easy disconnect. So i had to use an step-up convertor.
Now after some soldering and tetsing. The Yellow wire is the SPDIF jumper. And the cable poweing the device it's just an old mouse cable.
No more coil whine induced into the headphones because the Audio source and the DAC-OP Amp are connected with Fiber cable.
Hope this helps someone to give some life back into his SB0290!
Cheers!
Simplified schematic for the above.
