I'm trying to record some gameplay footage with OBS, and I have TeamSpeak 3 running in the background. Currently, all sounds (Gameplay and TeamSpeak) are all mixed together into one track. This is problematic for me, as I often need to edit what is said on TeamSpeak (remove coughing, irrelevant chit-chat, etc.), but that is impossible for me to do efficiently if TeamSpeak is recorded onto the same track as the gameplay.
In the past, I used Voicemeeter and Virtual Audio Cable to put TeamSpeak onto a virtual audio cable and thus on a separate track, but Voicemeeter changed the output sound somewhat, which I did not appreciate.
I remember reading - although I can't find the source anymore - that a dedicated soundcard might be the solution in this case. My plan would be to use the dedicated soundcard for the gameplay and the on-board soundcard for TeamSpeak.
Does this approach make sense? And if so, will I be able to use the same physical output device (i.e. my headset) for both? Or will I end up having to use Voicemeeter/Virtual Audio Cable anyways in order to output both on the same physical device?
