i can usually hear anybody with a invite into a private voice session, but in some games i can not hear certain people and others i can not hear anybody, and they can not hear me. nor does it show up that i am even speaking. yes i have checked to make sure the mute button is not on, hahaha. this was happening before i modded my 360 and is the same now whether i use my originals or backups of the same originals.
the 360 is running through my router via a wired connection, upnp is off and i even tried to forward the ports that the ms site recommends if having issues connecting to live, which i don't have problems connection to live, but figured i may as well give it a try - 88, 3074 but still have the same issues. my internet connection is 12Mb/s down / 1Mb/s up so i have more than enough bandwidth.
i can hear all other sounds through my home theater, just not the voip portion, which is quite annoying.
anybody else having this issue?
