Folks, I am trying to use this Intel D845PEBT2 motherboard for some audio
measurements, but the Soundmax driver (Cadenza) insists on loading a frequency
response equalization into all playback signals, even if "headphone" output is
selected. I am talking about more than 10db down at 150Hz and more than 10db peak
at 75 Hz, with rapid rolloff below that. I experienced an almost identical problem
on an Asus P4C800-E Deluxe, also using the Soundmax SW/HW combination. (Asus tech
support's first suggestion was to use the S/PDIF output instead.)
My understanding from the AD Soundmax site is that this is a "feature" to
compensate for specific models of cheap computer speakers. The manufacturer is
supposed to adjust the frequency response as needed to best work with a specific
model of speaker. In this case I purchased the motherboards by themselves and
assembled systems, so I'd like to decide for myself what my speakers need if
anything. But right now I don't want any of this distortion at all.
Anyone know how to turn it off ? There must be a file that I could replace or
delete that has these profiles, or perhaps just overwrite.
