Hi Sifus,

Last week we had some heavy rains and there was a lightning strike that caused a power trip in my home. It was pitch black before I went down to reset the power. However before I could get down I could smell wire burning smell. I made a mental note of it and came back up to see what happened after resetting the power. It became clear that my external speaker that was attached to my Desktop via USB was not working anymore. Found that the power indicator was blank on the 3 pin plug, so I knew that the 3 pin plug was burnt. It was of those cheap China made plugs without a fuse (I think). There were no screws to open and check if the fuse was blown so I guessed this must be the non-fused types. Anyways I bought the same type of plug again from Lazada for the same rating and received it today. When I replaced the plug I was happy that the speaker was able to be powered on. However there were no sounds. When I played on an audio file or the Youtube videos, there is no sound even though the speaker icon is under working condition and not disabled. We can also see the mixer bars moving up and down as the music played. Only thing is there is no sound coming from the speaker.

Here is what I did on my own;

1. Deleted the sound driver and re-installed it using the Device Manager.
    Didn't work.

2. Used System Restore to set the PC to an earlier date where everything was working.
    Didn't work.

The drivers had been updated to the latest ones. Still didn't work at all.

What went wrong and how to get the sound to be working again? I have attached the pic of the plug and the sound icon with the working mixer bar - to show that it works but no sound is coming.

Appreciate any ideas. Thanks a lot.
