What can be expected from analogue audio output of the MISTer (using the IO board). Does all cores support it and how is the quality?
@Sorgelig wrote in the Genesis Core thread, and I quote: "analog audio may get interference from other components. Also DAC used on I/O board is primitive. So you may hear some side signals like on old computers where you could hear how HDD is working through speakers"
Are the "side signals" something I can expect or is the analogue audio with the DAC on the IO board usually OK? From the schematic of the IO board I can see that the DAC uses passive components only. I guess that the audio signal coming from GPIO1 pins 2 and 7 is PWM?
I would prefer to use analogue audio so I'm looking into the options:
1. Buy the IO board or build the DAC part of it only for my project.
2. Buy an HDMI audio extractor.
3. Build a more advanced DAC.
I'm going to experiment myself but I figured it's good to ask since others probably have experience with this already. Grateful for any input!
