Solved Yet another problem; the audio system is often disabled after boot up

[Syncopator]

The 'speaker icon displays a red warning.

If I look in Device Manager, the High Definition Audio Device properties window says that it is working properly.

I have to disable it and then enable it. The red warning then disappears from the 'speaker icon.

Hi Syncopator, Have you tried this

Click start orb

Click Control Panel

Click Hardware and Sound

Click Sound

Audio devices will come up, right click on the device you wish to set at default.

Hi Syncopator, Have you tried this

Click Hardware and Sound
Click Sound

I don't have that anywhere on the computer. All I have, via Device Manager, is "Sound, video and game controllers", which has one entry, "High Definition Audio Device".

Hi Syncopator, The link below shows you from the start menu, where the control panel is to the right.


Start Menu All Programs in Windows 7 - Restore Default Shortcuts

This is what "Sound" shows me. It doesn't help me at all.

Hi Syncopator, Have you typed services.msc in the startmenu search box.

Check Multimedia Class Scheduler is set to Automatic Startup

Windows Audio Endpoint Builder is set to Automatic Startup

Plug and Play Automatic Startup

 

[Syncopator]

Yes, they're all set to automatic startup.

Hi Syncopator, I have been reading on HP's site and the audio driver it is showing for HP Compaq dc 7900

is ADI HD Audio Driver for Microsoft Windows 7. I just thought it was something else to look at.

Thank you for that. Although my PC is a different model, HP Compaq dc7900 Small Form Factor (sic) PC,they both have the same audio driver.

I had searched for an updated driver via Device Manager but the system said that the best driver was already installed.

Nevertheless I have downloaded the one from HP's site. Let's see if that cures the problem.

After uninstalling Malwarebytes I got rid of this problem and sorted out another.
