I have a HP Pavilion a6442uk PC running Windows Vista Home Premium SP2. It's connected to a HP w2207h monitor with inbuilt speakers. Realtek High Definition Audio is installed. Everything has been running normally for several months until yesterday when I discovered that the sound was not working.
When I attempt to play a disc or any music/sound from Media Player or the Internet no sound comes through the speakers. When I click on the speaker icon it shows that the speakers are on and sound waves are shown, indicating that sound from the external source is being received. I have checked the audio connections and these are OK. “System Information” shows audio to be working normally and “Device Manager” shows the Monitor, Sound, Video and Game Controllers to be working properly.
I'm at a loss to know what's wrong. Can anybody help please?
I have a a6642 too. I have 5.1 speakers tho so not the same set up. In the system tray you should have a brown speaker icon for the sound manager (it may be hidden so expand your system tray). Right click and select sound manager. You need to check that it is configured correctly and it will also indicate which cables are connected to which socket on the pc. You can test from there.
I've already checked and rechecked all the above and as far as I can see everything should be working normally - but it just isn't. The ordinary tray speaker icon and the brown Realtek HD Audio Manager indicate that sound is comming through, I just can't hear it. I've turned the volume up to full, turned all the Windows sounds on, unplugged everything, plugged it back in again - NOTHING!!
