- Odd Noises When Using 96/24 "Rapture" Upgrade DACCard.
The DA-10 Motherboard's +5VDC power supply can run a little low
when powering the 24-bit DVD-A DACCard. This
can result in no signal, or a garbled signal, or hissing noises in one
or both channels. The solution is to remove the DACCard, locate R101
and solder a 10K ohm 1/4W resistor in parallel with it.
