I haven't posted here in the MSFN forums for a while, but I have a problem here. I updated to VMware Player 6.0.7 on my Windows Vista host machine and for some reason, I can't get the sound to work on any of my guest OSes (Windows NT 3.51, Windows 95 and Windows 2000) that requires the legacy Sound Blaster 16 emulated sound card. For example, I've been running Windows NT 3.51 SP5 as a guest OS and although, the OS installs the Sound Blaster 16 emulated card, it doesn't work at all! Edit: Nevermind! I solved the problem. I had to uninstall r277 of the Realtek High Definition Audio drivers and revert to the audio drivers that came with my ASUS motherboard. The end result is that the sound in VMware now works! Incase, I ever decide to update VMware Player or reinstall it, I may have to reinstall the audio drivers again.
