no i don't use onboard i have motherboard z97 pro gamer and i have audigy rx sound blaster as sound card
Same thing applies, makes sure your audio settings are set to stereo and you're using the highest possible audio settings in general, using the sound blaster software. Don't use the HyperX adapter when listening to music regardless, it will make the audio quality worse.
I'm not sure if the Audigy RX has better audio than the Z97 Pro Gamer does though....
