Hi! I run XPAX on a network machine, but I can't adjust the loudness. When clicking on sound off or try to adjust the sound volume on the video screen nothing happens. Rewind, forward, stop and play work.

Hi,

Not sure what the problem here is but it may be related to Windows Media Player.  Please open a ticket at http://support.hifitechinc.com and we can assist with troubleshooting.
