I can hear music in SL therefore my headphones work and the general volume setting is ok. I have gone to ....voice echo canyon....and can not hear myself ....though others can hear me therefore my microphone is also working. With a working microphone and head phone speakers what would cause me to NOT be able to hear voice chat? I disabled voice chat then reenabled it. This did not help. I moved the sound for voice chat from its default of half maximal up to maximal and this didnt help. Its as though voice chat is on mute though I am finding NO option to mute all of voice chat. I see the white dot over my head and over the heads of others change to green as we talk. I hear none of it. Suggestions? Hopefully I found an answer. Other than Me ...Preferences in the upper left....and the Chat button on the bottom menu...there is yet a THIRD area controling Voice Chat Sound. In the upper right under the X there is a sound icon. Click that and IN THERE is a box which must be checked otherwise Voice Chat is MUTED. There is also ANOTHER volume control slider in there for voice chat. That volume slider setting seems to match the one found in Me ...Preferences...so Im assuming you can set that EITHER place. The check box which seems to set mute and unmute voices as far as I have found on digging for 2 days is found no other place. Hopefully this will solve MY problem. If not I will adendum this again. I will leave this post up so that OTHER people may benifit from what I found. I STRONGLY suggest that this information be added to all newbie orientations. I visited MANY orientation sites hunting for an answer, the SL web site, AND online live customer support and could not get an answer. I noticed that sound icon by accident as I was reaching up to the upper right to close SL to reboot.
