So I kept reading some more wondering why I wasn't
getting digital-domain clipping and I think it's because the driver prevents the output from clipping? Or are digital-domain clips just outright lost information?
If you look at the level meter in Windows, you can see when you hit the peak output. While it works for all channels at the same time, if you test only one channel however, you will see the output level for just that channel.
Now using the channel test (a short musical blurb, if you will) you can see the level meter flash and hit the peak when the music note hits the peak. But if you boost the channel level in "room correction" you just see the bar go "more solid". I tried it for one of the main channels because I figured clipping would be more audible there and though it sounded overall louder, the peak I don't think it's any louder, hence the no clipping.
So anything that is 0dB stays there, something that is -10db will be 0dB and something that is -5dB just goes to 0dB as well. So really, I'm thinking, all I'm doing here is compressing the dynamic range! LOL.
This is in contrast to the analog outputs which will distort using the same test (which is stupid because the line voltage is still low but that's another story altogether).
In this case I'm compressing the sub channel by dialing it up to "+10dB". I haven't really fixed anything at all, lol. According to what I've read an LFE signal that is 105dB, should be reproduced as 115dB, but I'm still getting 105dB. So this explains why the output still didn't sound "quite right", I've just compressed the sub channel so that sounds that are 10dB below the 0dBfs level are boosted by 10dB and anything above that is just boosted to
Roger, if it wasn't for this explanation:

I would not have come to this conclusion on my own, lol.
So while I haven't fixed anything I guess compressing the dynamic range of the LFE channel is about all I can do to make it better.
I could set all my speakers to LARGE in the AVR, forego any bass management and then set the sub level to +10dB, but I'd have to remember to lower the sub for every other source (and raise it for watching BD/HD-DVDs). Man this 10dB LFE bug really sucks!
I think I'm just going to stay with my ghetto fix of compressing the sub channel as it at least sounds better
if not proper
