I have my ps3 and xbox360 connected to the audio in on my audigy sound card through a splitter. however, the ps3 sound is very light, i have to crank my speakers up relatively high to hear anything (past mid point on klipsche speakers). obviously if my PC makes a nose, it will be supppper loud. the xbox360 sound level is similar to my pc sound level. how do i change the ps3 sound level? i didn't see anything in the xmb control panel that allows me to change the sound levels, nor did i find it under sound settings.
