VMware Tools provides the VMware Toolbox application to configure the time sync option for the guest operating system. This works great with Windows guests or Linux guests using the X11 GUI.
However all my Linux guests run without the X11 GUI. If you know the current setting of the time synchronization option you can use one of the following commands.
To turn time sync on
vmware-guestd --cmd "vmx.set_option synctime 0 1"
To turn time sync off
vmware-guestd --cmd "vmx.set_option synctime 1 0"
You can also do this from the Windows command prompt.
To turn time sync on
vmwareservice --cmd "vmx.set_option synctime 0 1"
To turn time sync off
vmwareservice --cmd "vmx.set_option synctime 1 0"

I could never hear anybody with the AT&T AudioPara4 file. I performed the registry tweak to switch to the stock AudioPara3 file. You can use Diamond Tweak to accomplish this as well with the 100db European Limit tweak. This improved the volume but distorted the speakerphone at the higher levels. Read more…
