It had Bassboost and the volume was loud and good. My previous board was an ASUS A7V266-MX with SoundMAX, it was OK but lemme tell ya much much better than this Realtek crap. It does use the HD Audio Driver, but it's crap. I did not find that option in either Sound Properties in Windows Control Panel or Realtek Contro Panel (which is very very ugly and borky) (THAT ON XP). Quote from: Bourne on 01:41:36 I have installed the Realtek 1.85 latest pack driver. It is probably a result of the bass cut filter that is intended to protect 1-2" laptop speakers. My guess is Realtek decided that the cure was worse than the disease, and left the 8kHz artifact in later drivers. When the sine sweep passes through that frequency band in the v1.60 drivers, the noise floor jumps 40-60db, and there is an audible "swooshing" when headphones are used. The hump at 8kHz in the v1.85 drivers may look bad, but it's a LOT better than the notch filter that I think was used to flatten it in the v1.60 drivers. Hopefully, Realtek will fix their drivers so they look at the full-range speakers check box.
But I would like to try headphone virtualization with normal bass response one day. I'm not a fan of DSPs mucking with my audio stream, so this isn't a huge loss. Of course, this disables all those potentially useful effects such as surround sound, headphone virtualization, environment effects, equalization, etc. The blue curve is produced by checking the "Disable all sound effects" check box in the enhancements tab of the speakers properties control panel. In version 1.85, the surround sound check box changes to headphone virtualization in the HD audio manager control panel when headphones are plugged in, but the frequency response is unchanged. And for v1.85 drivers, plugging in headphones has NO effect on the frequency response, even though the drivers know headphones are plugged in. However, the full-range speakers check box has NO effect on the frequency response. The blue curve should be the frequency response for full-range speakers or headphones. In both images, the red curve should be the frequency response for limited range laptop speakers. The second image is for the Realtek v1.85 drivers. The first image below is the frequency response for Toshiba's OEM version of the Realtek v1.60 drivers. If your Windows Vista Realtek HD audio codec has poor bass response, the following information may be useful.
