Lenovo C20-00 A10 All-in-One (No sound from Speakers)

Looks increasingly likely that the speakers are simply disconnected, possibly damaged.
Fiddling about with drivers/software/diagnostics will not resolve that.

I agree. The fact that the speakers show as working in properties means the drivers are ok. It looks like physical damage to the connections.

One way to confirm that is to create a live boot disk (free, Google) e.g. Bob Omb's, Hiren's...

Create a bootable disk from the downloaded iso file (one of the tutorials here on creating a bootable disk can help- see e.g. Rufus instructions).

Boot the PC from that and then see if speakers work.

Do you definitely know they were working before you reinstalled Win 10?

Went on to my favourite poertble site and downloaded AnkhTech WinPE 10 and Parted Magic, when I ran AnkhTech WinPE 10 and tried to play a .MP3 it brough up Winamp and the an error message



Parted Magic gave no error

Yes, I am sure they were, so I am going to take the cover off and have a look to see, if I have pulled a wire out. I will have to see if I can get a replacement set.

But thanks everyone for your help. Will keep you updated

Don't use a 3rd party program with a boot disk unless it's truly portable or included. Simply use the sound test in Windows as earlier.

I've never heard of the boot disk you mention.

sound solution!
