I have an IDT High Definition Audio Codec soundcard which works correctly, and doesn't have ANY options, BESIDES volume, and choosing if you want 16 or 24 bits audio, with 44100Hz or higher (up until 192000Hz).
And I turned the power switch on, on the control panel itself AND the Equalizer. But still, nothing.
It doesn't have
any options? At all? Well, that's beyond weird. Now, I've spent quite some time doing some research on the Internet on this, since I have no experience with an IDT driver (only Realtek and my own), and what I've been reading up on is that you might have to update your soundcard drivers. The appearance of an Enhancements tab is actually up to the audio driver whether or not it supports it. But even without an Enhancements tab, V4W
should still work (unless all enhancements have been disabled, which IIRC isn't by default).
Also, does your computer have any proprietary software used to tweak the soundcard (like Beats Audio or Crative Audio Control Panel)? If so, you might be able to tweak your settings from there (but I have no expereince with such software, so I can't say for sure).
Another thing: did you tweak the EQ at all? Turning on the power switch won't do anything until you tweak it, you know. Just saying.
Since evidently, V4W is causing a lot of trouble for
both of us, I do know another which might be to your interests. There is a program called SRS Audio Sandbox which pretty much adds another sound device to your computer through which your main audio will go. It's more straightforward to install, but you will have to pay about $20 for it. That, and it's not really an equalizer
per se, but it's more of a gen-com-oriented sound enhancer which should satisfy most people's tastes. Audiophiles...not so much.
I don't know if I could be able to help you solve your installation problems with V4W, as from what you have stated there shouldn't have been any gripes. The lack of an Enhancements tab means you simply skip the step (the developer said so himself). I'm sorry I couldn't help you any further from this point, since I don't have any experience working with the audio driver that you use.
