Since I’m personally interested in using soundcards that support tone (bass / treble) adjustments and I’ve noticed this information is particularly difficult to find online (and manufacturers rarely mention it in their specifications) I’m posting screenshots with the software functionality and controls of the cards that I’ve personally tested and/or used, for anyone else that may be looking for this same information.
First stop is the Sound Blaster Audigy 5/Rx:
I will update this post or publish separate ones for other soundcards.
