Hi Bruce
Thanks for responding....am using Windows 7 with Phd 2.5.0 ( will update tomorrow).
Yes tones test fine in the speakers...internal speakers. Audio alarm absent both as local operation and when connected remotely....I use to hear it locally in the obs when connected remotely, I use a baby monitor beside the laptop so I can hear the lost star alarm ( its my cheap cloud sensor!).....or use to be....
cheers
Well, I suspect this is going to be a challenge. :-) I absolutely don't want to drift into one of these support dialogs where I ask you to be sure your computer is plugged in - we all love those. <lol> But maybe you could just march through this specific dialog. In Win7, go to Control Panel, Hardware and Sound, then click on the 'Sounds' tab. You should see this dialog:

The arrows point to the things that you might look at – the ‘Test’ button lets you play the sound. The Windows Ding.wav sound is one of the faintest ones in the list on my system and can be quite hard to hear. You can temporarily change the “default beep” to a different sound if that helps. This would indicate whether the problem is with the specific sound or is related to the triggering event.
We had a similar complaint from another user on the Stark Labs forum and his problem just disappeared when he went into this dialog and poked around a little. Very odd. For now, we don’t see how it can be a PHD2 thing but are wondering if a Windows update has caused a problem.
Let us know what you find,
Bruce

Hi again Lynn. The other fellow just posted that he found the problem - the "system sounds" in the volume mixer had been magically muted. Worth a look if you haven't already been there...

Still playing....I opened the Wav files under Windows - Media and they all play through the speaker when opened with Windows Media Player. Still no joy in the Control Panel under Sounds with Test button.
cheers
Lynn
