Mirage 4000 Power Tower audio problems

Check the -12 volts in your new PSU.

PS-the serial port, works?

@doctorq

audio and serial port, uses both the -12 volts line.

Never heard that CSPPC, could make problems, with the serial port.

Check if your Mirage PSU (standard ATX PSU), supplies the -12 volts correctly.

PS- take a look at "Putting the A4000 into a Power Tower Mark II" thread. The problem is the same.
