OK... finally got my PC hooked up to the AVR via HDMI (for video) and optical SP/DIF for audio, downloaded drivers for the built in Realtek audio chip, and fired up REW. Here's my first in-room FR graph. I realize the SPL levels are a little high but I wasn't going for max SPL or anything. I'd have to figure out how to make REW start the sweep at
no lower than 10 Hz for that!
