Oops... After such spectacular results I should have left well enough alone... but, I decided that I might experiment with a more aggresive filter set to catch that dip at 70hz and try a house curve.
Problem is once I unhooked all the gear so I could watch my HTPC through its SPDIF digital out and have now rehooked up all the REW input/outputs, etc. I have something goofy going on.
I've run through the usual soundcard preparations (meaning I've set the speakers to stereo, disabled the SPDIF output, made sure the RS meter is connected to the blue, and my green output is being stereo to mono split out to my AVR. I've even unhooked the SPDIF output and unplugged/replugged my analog output plugs (green)--even repeatedly rebooting the HTPC to make sure my soundcard is auto-detecting appropriately.
What's happening is that I'm getting some pronounced fuzz from my front R speaker and when I turn up my volume much to get my SPL at 75db I begin to get feedback from the RS meter! I'm also getting that loop effect in my graphs like before--sounds like I need to turn off something in my record mixer, right? Well, I've been trying that with no results. I have the line in selected and nothing else. I have gone to my AC97 UI and turned off the digital output and selected stereo and no soundeffects.
Still, everytime I reboot I end up having to reselect the AC97 soundcard--and when I go to start REW it has a screen that says I have no input mixing drivers (something about PCM stereo). Here's the screenshot:

Help!
One more question also--how do I turn off, delete filters? I know how to set them, but what do I do if I want to ditch old ones (e.g. I had originally 4, but then overwrote those with a new 9 a couple days ago)--how do I go back to those original 4. I know how to overwrite the first 4, but what about the last 5? Is there a way to turn them off?
Thanks as always.
