so my sub is normally fine, but i just setup my home theater system to the htpc i just built, all speakers work fine and sub works. but the sub is very weak.

Is there any reason why the sub would be weak on the htpc but not for media streamers, bluray players etc?

YAMAHA RX-V573BL 7.1
Polk Audio PSW Series PSW505 12" Powered Subwoofer
ASUS H87M-PRO LGA 1150 Intel H87

Using HDMI from MB to reciever for sound. Any ideas what could be making the sub weaker then normal?

Which software are you using for playback? With JRiver Media Center you can adjust the outputs for all your channels individually.

Source with little or no base info? Certainly not a 5.1 track, and hard to say how the base is being mixed between speakers and sub.

Sounds more like a source and receiver set up problem more than a HTPC problem.

You need to test DD or DTS on the HTPC to compare to your BluRay player.

Many receivers have separate bass management depending on the source. Also on the receiver you need to set all speakers to small.

Read the AVR manual. There is a setting for the subwoofer to generate sub feed from source that is not 5.1, which youtube is most likely not.

Some call it LFE+main or something like that.

Does not sound like a PC issue at all.

6 TV's in the house on FiOS and we only pay $4.99/month to connect them all!!! Power to the CableCard and WMC7!!!

Agree with most of the above. I assumed it was movie playback from bluray/DVD/files.
