Hi,
“error opening audio: Illegal combination of I/O devices” input: ASIO: Realtek ASIO output: MMIO:Speakers (Realtek(R) Audio)
when using the portaudio backend (called "ASIO" in the menu), I/O devices must use the same audio API, but in your case you have ASIO for input and MMIO for output.
If I turn off the input device (uncheck) I am able to get a very distorted test tone.
When using the portaudio backend, MMIO is indeed broken (probably we do something wrong in Pd, I have to investigate). If you want to use MMIO, use the MMIO backend (called "standard" in the menu).
I think what happened is that previously you used the "standard" backend and then accidentally switched to the "ASIO" backend.
BTW, it's generally better to use the "ASIO" backend and select the ASIO driver of your device, in your case that would be "Realtek ASIO". If your device doesn't offer an ASIO driver (e.g. cheap soundcards), you can install a generic ASIO driver like ASIO4All.

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
