Windows 10: Lost PC sound output

I have lost sound output.from my PC. I have tried diagnostics with no result. It shows that there is output but this doesn result in sound. i have tried two different loudspeaker systems that give connection crackles as they are plugged into the PC by 3.5 connection.

Media PC lost all sound suddenly

Hope someone can help with this: have a media PC outputting to a TV through HDMI, both sound and picture. Worked fine up until yesterday, was ok in afternoon, turned on in evening and no sound, picture is fine still. Don't know if anything was updated when it turned on as it wasn't me that booted it up.

In the Playback tab of the Sound panel I have the TV listed, going through AMD High Definition Audio, which is the built in graphics chip. There is no activity in the output bar shown there on the right when things are playing. If I try and do any Test of sounds it instantly says Failed to Play Test Tone. Same happens if I try a Test on the Realtek Digital Output which is the onboard sound, but then nothing is plugged in to that so I don't know if that's as it should be.

Device manager says everything working ok. Any suggestions?

EDIT: if I try the Windows troubleshooter it says "Plug in the Speaker, Headset or Headphone. The Device does not appear to be plugged in."

 

Windows 10 audio stutters regardless of driver or output used, more noticeable on the toslink and surround sound.

• What device are you using? A laptop or a computer?
• Its a desktop, i listed the components in the original post.
• Do you have an external speaker?From which device does the sound come out from? From the TV or from the device?
• I listed the outputs in the original post. The issue exists on all outputs and exists on the tv speakers, surround sound speakers, and headset.
• What other troubleshooting steps have you tried so far?
• I have listed the troubleshooting steps that i can remember in the original post.

 

Good surround sound headset

I know you say you're not that guy, but stepping into the $250+ range really brings a change in build quality that might have you never having to buy another set. Otherwise, getting 6 speakers with decent sound in a headset is hard, and that's what you are asking for, and I have no suggestions, but just a bump up the list. *Stick Out Tongue
