A "snapshot" of DSP settings in Creative Audigy 2 drivers under Vista
I want to thank you on the great kX driver, latest version allowed me to install Vista and have crystal clear sound (I have Audigy 2 "classic"). When I used Creative's driver for Vista I could not listen to any music because distortion level was so high. Under XP, original Creative's driver gives normal sound quality, so I went back to XP and googled for solution (it happened to be kX Project of course).
Now I think that Creative supposedly lowered sound quality in Vista for sound cards older than X-Fi. Maybe they are setting the DSP in such way that it lowers sound quality under Vista. I can't hack their driver and find out, and as I have seen the kX DSP manager I started to wonder if it is possible to "download" all DSP settings from the card itself under Vista when there are only Creative drivers installed? Then we could know for sure that Creative cheats or not. Is it possible at all? Also, please take look at this snippet of my tests of Audigy 2 uder XP and Vista. There is something fishy going on: Windows XP: RightMark Audio Analyzer test report Testing device SB Audigy 2 Audio [D000] Sampling mode 16-bit, 48 kHz Interface DirectSound Testing chain External loopback (line-out - line-in) RMAA Version 6.0.6 20 Hz - 20 kHz filter ON Normalize amplitude ON Level change -0.2 dB / -0.2 dB Mono mode OFF Calibration singal, Hz 1000 Polarity inverted/inverted Summary Frequency response (from 40 Hz to 15 kHz), dB +0.00, -0.00 Excellent Noise level, dB (A) -101.5 Excellent Dynamic range, dB (A) 95.5 Excellent THD, % 0.0020 Excellent THD + Noise, dB (A) -90.2 Very good IMD + Noise, % 0.0040 Excellent Stereo crosstalk, dB -101.9 Excellent IMD at 10 kHz, % 0.0044 Excellent General performance Excellent Windows Vista: RightMark Audio Analyzer test report Testing device Gło�niki 48 (Creative SB Audigy 2 (WDM)) Sampling mode 16-bit, 48 kHz Interface DirectSound Testing chain External loopback (line-out - line-in) RMAA Version 6.0.6 20 Hz - 20 kHz filter ON Normalize amplitude ON Level change -6.3 dB / -19.8 dB Mono mode OFF Calibration singal, Hz 1000 Polarity inverted/inverted Summary Frequency response (from 40 Hz to 15 kHz), dB +5.51, -17.62 Very poor Noise level, dB (A) -103.3 Excellent Dynamic range, dB (A) 88.8 Good THD, % 0.013 Good THD + Noise, dB (A) -72.8 Average IMD + Noise, % 0.014 Very good Stereo crosstalk, dB -27.0 Very poor IMD at 10 kHz, % 0.018 Very good General performance Good

For me your test results under Vista look more like a driver bug and/or incorrect settings, not like something made supposedly.
--- Well, theoreticaly it is possible to snapshot everything. However i really doubt if you're willing to waste your next half of year for disassembling and reviewing a megs of logs just to find out if Creative is cheating or not... Doh! Would not it be more humane to just buy a card wittingly w/o "cheating"? (The DSP you can see in kX DSP is only a small part of the 'Audigy 2' chipset - there're tons and tons of other modules, configuration registers, initialization sequences etc. etc.). |

Yeah, I'll never again buy any Creative's card, that I know. My next card is going to be Audiotrak Prodigy HD2, but thanks to kX driver I saved almost 100 Euro for now (and yeah, I'm going to donate some of that to the kX Project). I'm afraid that my headphones (Sennheiser HD 495) won't allow me to hear a difference after installing Audiotrak Prodigy HD2

I also wonder how reliable/accurate RightMark is on Vista, with all the sound API changes and what not... ?? |

I think they would more likely just not make any drivers for Vista for these cards, then intentionally create buggy ones to try and coerce people to upgrade.
When I think about "Forced Obsolescence", DRM comes to mind (but that is a discussion for another forum). |

That is not exactly what I meant. I was thinking more along the lines of things to come, like perfectly good CD/DVD players not being able to play a CD/DVD because it was built before DRM, forcing you to buy the so-called latest and greatest, etc. Or you not being able to use your SPDIF output of your sound card (to connect to your home theater system or whatever, etc), when playing certain content because they simply do not trust you (to not record it and pirate it, etc). DRM is half the reason for all the audio (thus audio driver) changes in Vista. In any case, this is OT and (again) probably better discussed in another forum.

"planned" and "forced" mean the same thing to me, when it is someone's else plan (that strays far away from my plans)
