Olds....
What OS are you running?
I have been having issues with the AH.exe stopped working and stutters with the game so that it was virtually unplayable since the update/patch.
I spent yesterday and this morning wiping my entire computer clean, reinstalling Vista 64 Ultimate, and ONLY putting Aces high on it. I have managed to get the thing running but still having the crashes when I swap between arenas (for example: going from LWO to LWBlue....or going from TA to Late war arenas).
My microphone got very quiet. I went into the Sound area from the control panel and enabled the +20db boost. What has been happening the past hour is that for some reason this gets Kicked off and folks have a hard time hearing me.
I am sure you have tested this but when you are online you can type in your CPID in channel V and hear how you sound to others.
Have you tried this to double check?
Also.....are you using any sort of sound card besides what is on the MOBO?
I am using a Creative Labs XFI Xtreme Gamer soundcard btw.
Let's see if we can't get this figured out!
EDIT:
I have set the MIC boost to +20 but when I restart the computer, it goes back to unchecked. Not certain as to why this is going on. Frustrating to say the least.
