So I recently ordered a capture card and when I plugged the device up to OBS (As it's own instruction booklet said to), the sound comes out different than the one from the original sound. The clip I recorded came from my SNES, which is then plugged to a A/V splitter, then to an A/V-to-HDMI adapter, which is then plugged into an HDMI splitter, then the Capture Card, and then the TV (The card has a little dongle that connects to the PC via USB 3.0).
