I have read all 3 manuals, read every SSO entry in the forum and read every item in the SSO KB, but I can't find the answer.  The manuals state that there is a voice package with 19 recordings, but the recordings never play.  I understand that while in slew mode everything is silent, and when passing 82K the wind noise and frame groaning start, but I never get the voice transmissions.  I have uninstalled and re-installed the SSO twice, but that has no affect. I confirmed that the voice package is installed in the file FSX>Captain_Sim>sso and the wave files and sound.cfg file are there. I made sure the sound is turned on and the realism sound settings are normal. I'm running FSX with Acceleration. Please explain how I activate the voice package.
