Windows 7: Playing sound will just suddenly go silent unless I press volume/mute

Playing sound will just suddenly go silent unless I press volume/mute

This is problem that just one day came into being on my laptop running Windows 7. I can't associate it with any particular update since I don't play videos or sound files frequently.

Here's what happens. Let's say I got to YouTube and play a video. The sound will work for about 30 seconds to a minute. Then it will suddenly stop. The video still plays. If I toggle mute (press it twice) or press the volume up or down, the sound comes back but it doesn't last as long. To listen to something, I have to stand ready at the volume (one click up or down) or mute (two clicks) button to press it any time the sound goes away. The same thing happens if I play an mp3 on the music player. So it's not browser plugin related. It seems either sound driver related, or even a HW issue perhaps.

I just upgraded to Windows 10, using a completely different browser and the problem is still there.

Does anyone have any idea what might be causing this?

Thanks

What do you have listed for the sound? The actual hardware sound driver or the generic Windows installed High Definition Audio Driver? If you don't have the actual hardware sound driver, that is the first step.

There are two things listed under Sound in the device manager:
Conexant 20585 SmartAudio HD
Intel(R) Display Audio

That's the correct sound driver.
If you just upgraded to 10 and still doing it, could be hardware, sound driver (the Win 7 driver may not be Win 10 compatible or at least not 100% compatible). Check Lenovo and see if there is a later driver, at least a Win 8.1 driver.

Hey so I have (what I think) is a basic question. I listen to the radio on my work computer. What I am trying to do is have it so the volume is on mute all the time, but when I plug in my headphones it un-mutes. Then if the cord comes out by accident it goes to mute without playing any sound....
