No Sound on Pavilion P6347C Desktop PC w/ Windows 7.

[ronb300]

I had my computer in storage for over 2 years.  it was working great.  Sound was fine.  My wife's laptop broke and she needed a computer ASAP.  Hooked it up. I have no sound at all.  Everything works but the sound.   I downloaded HP Support Assistant. Ran it a few times. Assistant says everything should be working, but isn't.  I tried their Advanced diagnostics uninstalling drivers and reloading.  Someone said to check  Windows Audio, Windows Multimedia Class scheduler, Windows Audio Endpoint builder, Plug and Play, and Remote Procedure Call (RPC) to see if they are enabled.  They all were enabled. I disabled them, then enabled to see if that helps.  My Bios is 6.0.1.7736 if that helps.  The advanced says to reset bios to default.   Everything I did, Still no sound.  Is there a Setting I can Change in the Registry that might help?  I've had other computers in the past, where I thought all was lost, and it was a registry problem.  I was hoping to upgrade to Windows 10 to see if it helps, but I have programs I spent a lot of money and now retired and most disks are warped from our Arizona heat, where they may or may not work in Windows 10.  Help! I'm missing something!

Thank you for posting on the HP Support Community.

• is there RED x or Exclamation mark on sound icon?
• Have you tried earphone or other Bluetooth audio devices to check the audio output? 

I have a few troubleshooting steps we could try to fix the issue:  

Use the troubleshooting tool in Windows

The audio troubleshooting tool in Windows can automatically fix common audio recording and audio playback problems with your computer. Run the troubleshooting tool using the following steps:

• In Windows, type find and fix audio into Search, or right-click the speaker icon  in the taskbar and select Troubleshoot sound problems.
• Select Find and fix audio playback problems or Find and fix audio recording problems from the Search results.
• Click Next.
• Select the device you want to troubleshoot and click Next.
• Wait while the troubleshooter detects problems and makes changes (or prompts you to make changes).
• When the troubleshooter is done, the Troubleshooting has completed page is displayed, listing any problems found and what changes were made to the computer.
• Click Close.
• If a recommended action is displayed, select Apply this fix.

Restoring the audio driver in HP Recovery Manager:

1. In Windows, search for and open Recovery Manager.
2. Click Reinstall drivers and/or applications.
3. Select the audio driver in the list, and then click Install.
4. Wait for the driver to reinstall. When the installation is complete, click OK.
5. Close HP Recovery Manager and then restart your computer.
6. Test for sound. If the audio problem persists after reinstalling the driver, try updating the driver using Device Manager.

Hope this helps! Keep me posted for further assistance.
