I would hazard a guess that the Asio/mmio input/output combination is the problem. Does the ASIO:Realtek ASIO output option work? Have you run the "Sound settings" troubleshoot tool?
I found the distorted output to be related to block size and delay values in pd prefs/audio settings. Making those values larger cleaned things up.

Hello list,
I wonder if someone here can give me some advice.. I am in a situation where I need to run PD in coordination with Processing on a high end windows machine running Windows 10. Everything worked perfectly until this morning. Now PD’s audio is not working at all. Audio from a web browser works fine. Audio from Audacity works fine although I don’t see any options for an input audio device (not that I have one plugged in).
When I open PD and run test audio midi I get this error message: “error opening audio: Illegal combination of I/O devices”
When I open Audio settings, I have: input: ASIO: Realtek ASIO output: MMIO:Speakers (Realtek(R) Audio)
There are no other input device options.
For output I have these options: MMIO:Microsoft Sound Mapper - Output MMIO:Speakers (Realtek(R) Audio) MMIO:PHL 276E8V (2-NVIDIA High Defi MMIO: Digital Audio (S/PDIF) (Realtek ASIO:Realtek ASIO
If I turn off the input device (uncheck) I am able to get a very distorted test tone.
This problem seems to have started soon after I tried changing my screen resolution and then changing the pd font size and stretch options. I don’t know if this had anything to do with the problem or not though.
I have tried reinstalling PD a couple times and reinstalling the Realtek drivers.
Thanks for any advice.
Cheers, Rick
