What version of HostMonitor do you use? RCC version?
I suppose, you have not enabled "Perform “play sound” actions" on RCC's side. Quote from the manual:
http://www.ks-soft.net/hostmon.eng/rcc/index.htm#start
================
Perform “play sound” actions
With this option enabled RCC replicates “Play sound” actions that were initiated by the HostMonitor and plays those sounds on the system where RCC runs.
You should specify path to “bad” and “good” sound files (WAV, MID). These files must be located on drive that is accessible from RCC system (system where RCC is running).
Notes:
1. If several test items changed status simultaneously and HostMonitor played both (“good” and “bad”) sound files, RCC will play “bad” sound only.
2. Even if “Play sound” actions were configured with “Show Wakeup window” option, RCC will not show “WakeUp” window unless you enable “Perform ‘show popup window’ actions” option as well
================
You may access this option by clicking on "More options" button in RCC logon window.
