Hi, I am using pure data with the asio4all driver. Sometimes when I open Pd there is no output driver selected and I have to select asio4all again. Does anyone know why this happens??

Some time ago I bought an apogee interface that its controllers don't get along very badly with Pd and I'm forced to use asio4all, but I don't feel it gets along with pd either. All these problems with asio drivers come since I upgraded to windows 10. I would like to know if any of you have had similar problems with windows 10 and Pd or if there is a certainty that windows 7 has behaved better with pd than w10. I'm at a point right now that I don't even want to imagine the problems if I upgraded to w11. I wish it was just my problem, but I'm afraid it's not.

@EMR66 Asio4all has been updated a few times for Windows 10 and 11.
If you hadn't seen the updates they might be worth trying.

when the amount of Audio devices gets changed (especially when new ones are added, and I count virtual drivers as hardware) it can get confused about what it is - things like turning monitors on (monitors have frickin sound cards) or connecting bluetooth devices will futz with it.

Pd runs cross platform and almost nobody who develops for it actually uses windows so I just live with having this happen on occasion. Pd's really easy to go change those settings btw - can have dsp running and change the rate. Typically if the device is there it will try and remember but I - maybe once a week end up having to go in and change it. Remember to hit save.

Another tip with windows, once you have all your monitors and sound cards set up to the default you like - reboot the computer once, it will make its best effort to remember all the settings when you do this.

Thanks for the answers. I am using the latest versions of Asio4all and Pd. I would like to ask you a question that may be a bit far-fetched. Right now I use Pd to process white noise using [noise~] with plenty of [osc~] for "ring modulation" and going through a multitude of filters. I use [vline~] and [line] on most oscillators and filters to change the frequency. My question is: Would it be feasible to use the MME controller to process all this without problems or is it totally inconceivable? I know that when recording audio or playing a MIDI instrument it is almost unthinkable to use MME when ASIO exists due to latency, so I imagine that latency would affect me too when working with [vline~] and [line] or Could I be missing something in terms of how these tools work? Thanks greetings!

@EMR66 yeah you can use MME - it sounds the same but it adds a noticeable amount of Lag/delay for times between when you either process live audio in with [adc~] - from what you create or hear in the moment until it comes out of PD - or when interacting with UI (moving sliders, you will notice you hear it change well after you move it), or using a midi keyboard (press a key and instead of feeling like it happens right away, it seems to be delayed, thats lag). It can be offputting when you are intereacting in a way you expect a responce - but in possibly really slow evolving generative audio it might not be that noticeable.

An option to consider is getting an external usb audio DAC which will do asio and has been to me - more reliable for Pure Data to recognize - but in general my advice is the more you just keep working with what you have - the hardware or software - it just seems to settle in, do what you want it to, and become more reliable.
