Wow that was weird, i was then talking to someone about Alanis Morisette and how ‘Ironic’ rain on your wedding day actually is - and here i come to read this 10 minutes later. Think we’ve fallen into the matrix lol.
So, are you saying you are using different speakers? It’s hard to really know what your routing is here.
But just remember that an ASIO driver will have different routing internally than a Windows driver - This means a possibility of different volume level, and also the windows driver could have some form of EQ or spatial effect being applied - either by the windows spatial mode itself, or a third party sound tool. (Check your system tray bottom right).
There’s also the possibility that you have multiple drivers for the same audio interface too.
Trouble is, without fishing around on your machine for you - it’s very hard to say what is up here. Could you take an image snapshot of your sound control panel? Open up ‘Run’ in windows and paste in:-
There’s mine as an example, you can see in there that this laptop came with ‘Nahimic’ pre-installed and if i use that device it will have EQ/3D spatial effect applied to anything i play in windows… But using Cubase the ASIO driver will be used so won’t be subject to those effects.
Just curious if your machine has such devices defined too, and you may not be aware.
