Calibrating Volume with an SPL Meter

[Naylia]

I'm calibrating SPL on my reciever this weekend and that should be a piece of cake. However, has anyone given any thoughts to calibrating their HTPC as a source that is roughly inline volume-wise with any other sources used, so that reference volume is really a reference across all your sources.

I figure, first disable system sounds in Windows so that they don't annoy you. Then I'll set Windows Volume Control at 100% (this is rumored to have the least distortion of the audio signal). Next I'll calibrate the volume of Winamp using a white noise wav file. But what abou SageTV? Does anyone have any thoughts on how best to adjust the volume of tv? Does SageTV even have it's own internal volume control? Should I just play with the tweak tool for my pvr card and attempt to get tv volume similar to DD volume? Any thoughts....

I just run the digital out and don't use the volume control on my HTPC at all. In fact on my soundcard (Revolution 7.1) it's disabled for digital out.
