Dear
@Suslik V , thank you very much for your help :)
I already now this article but those versions do not help, unfortunately and timewise I can not rebuild a
version myself at the moment.
Probably this is not the only problem. I was so much hoping that the surface pro 11, that says it has better performance than than a mac with an M3 processor would at least record 4 simple audio devices in good to normal quality and one video stream over capture card (only 1080p) with probably a normal webcam.
I wanted to use this device also for streaming out to twitch for example but it has not consistent quality.
Eve the monitoring is stuttering and I hoped that Obs works on an official build, probably.
These devices would be very helpful for small studios or streamers that want to have a plug and play solution without noise and easy to construct a two computer setup.
My hope was that a similar effect would happen like when the Macs with M1 processor started to come out but Arm64 Windows seems to be out since a while and maybe the main problem is microsoft.
Thank you again very much for your help.
I will continue to find a solution and maybe find out if the Arm64 build can be modified but I think there are many processes in the background that cause the big problems and it is probably not Obs.
