Hello. In the past week, I have had to purchase a new PC for the first time in like a decade. (Yes... I know.) With that, I had to make a decision on whether to go with an internal souncard or an external Audio Interface for the new computer. I went with a Focusrite Scarlett 6i6. From a playback / output perspective, it seems to work well. But, I cannot figure out how to record something that's internal (that is, not coming into the unit from an outside source). For example, if I want to record the audio that I hear when playing a video on my PC (Youtube, DVD player, or otherwise). With my old PC, I had an internal Creative Labs Soundblaster card. In the mixer settings/options, I could choose things like "wav" or "what you hear" as an input source for all recordings. It allowed the DAW or any recording device in the PC to record a direct feed of whatever audio the computer was playing. It worked great, in perfect replicated quality. With these Focusrite Scarlett units, your inputs are chosen/routed through their "Scarlett MixControl" software. I cannot figure out a way to choose any internally played audio (from a video, mp3, or wav - for example) as the audio source to record. Is there a way to do this directly with these Scarlett units without some convoluted form of running wires outside the box and then back in again? It appears that I can only choose the physical Focusrite unit inputs as an audio source. Any advice would be much appreciated. I have watched online tutorials and have read the manual. But, I cannot figure out a way to do this for the life of me. Thanks, in advance, for any feedback. .
