Why the heck are PS3 games so loud compared to Blu and 360

[Matt S]

Trying to see how close I am to all of this

From what I call tell: 360 supports digital audio only; PS3 will support PCM (if receiver handles it via HDMI which mine does) and blu movies via PS3 do the same

what bugs a bit, when I used just my tv, I played everything at the same level- more or less. Now that I use a receiver with all these fancy audio format options, I play:

Blu movies at level 47 of my receiver
PS3 games at 39 (they are noticeable louder than everything else)
360 at 45

I did test Dead Space on my PS3 and 360 and both sound great via 5.1, however, the PS3 version was much, much louder and system had to be turned down

Anything I can do to adjust this directly on the PS3...Sure, I can turn it down no problem. Just trying to see if many have different level issues depending on format/system?

Thanks
