Low weapon firing volume

Downloaded ODST today and noticed the weapon firing volume is way too low. Everything else is at a good enough volume… same problem with halo 3. Turning up the tv volume, just to hear the firing, just makes everything else louder (i.e. radio chatter). The silenced smg (at current volume) sounds like an automatic squirt gun. Please… turn it up.

Anyone else noticing this issue by any chance?
