Some persons like myself have ATI/AMD graphics cards with HDMI output. At times you may end up with a monitor (or TV) that has HDMI in and you can use the speakers on the monitor (or TV) for sound. Problem is, after some update of the driver you may find that the sound suddenly stops working. If you had sound before or just installed the latest driver and suddenly have no sound, here is something to try.
Please note that this is a last resort. One of the first things you should try is locating an older graphics driver online then installing that. If that still doesn’t work then you may proceed with the 8 steps below.
Open the sound properties for your playback devices. Do so by right-clicking on the volume icon in your taskbar then going to PLAYBACK DEVICES.
Click on your HDMI device and then go to PROPERTIES. If you have more than one HDMI device just ensure it’s the correct one afterwards by checking if it says ATI or AMD.
Click again on PROPERTIES on the next window.
If applicable, click on the CHANGE SETTINGS option in the next window.
Click on the DRIVER tab and look for one of two options. If you have the ROLL BACK DRIVER option then chances are you had the sound working before. If that option is not clickable, then you probably just installed the latest driver. At this point you click on ROLL BACK DRIVER if it’s available and then OK on the remaining windows then test your sound. If you don’t have the ROLL BACK DRIVER option (or it didn’t work) then move on to clicking the UPDATE DRIVER option then going to STEP 6.
Click on the option that says BROWSE MY COMPUTER FOR DRIVER SOFTWARE.
Click on the option that says LET ME PICK.
Finally, you should see multiple drivers available. Note the version numbers – in my list there are 4 versions available. Two of them are 7.12 while the other two are 6.1. Make a note of the last digits in each and the dates. At this point you may try from the oldest version to the newest.
After completion you should be able to hear sound from your HDMI device.
