Sorry to hijack this a little but I am new to PC gaming, if you plug in the USB dongle does this automatically cut off the soundcard output sockets or the PC case headphone sockets?
Reason I ask is I want to maintain a dedicated sound output while using headphones to provide a signal for my buttkicker
No, all soundcards will be active at the same time.
In windows you select a "default device" where all system sounds, Spotify, Chrome etc automatically switch to.
Then you have applications that let you select the sound output device. Assetto corsa for example.
If you unplug the cable from onboard Realtek cards, they will shut off. But that shouldn't be important for you.
So as long as the applications that are planned to send something to the buttkicker can select a sound device (I think all can do this!), you're good
Jfyi to prove my point:
I have the Realtek onboard active with a dummy plug to send background recordings to it while listening to something else.
(recording a replay in windowed mode via obs while doing something else).
I then have a focusrite studio usb interface with microphone and main speakers plugged into that.
Then my TV via hdmi, which becomes another sound device when I switch it on.
And lastly I have a Bluetooth stick that shows up as a separate audio device for when I want to walk around with my Bluetooth headphones.
