When I disconnect the power cable, music continues
How is this possible? Can a virus start on residual electricity left in the PSU?
No virus or anything else can operate on a system without power, assuming we are talking about a desktop system (i.e. not a laptop, etc with battery) not operating from a UPS.
Where is the sound actually coming from? Your speaker arrangement is not clear to me, are the only sound producing devices in the system the TV speakers? Does the sound emanate from them? If the computer does actually have any speakers attached, it's possible for them to pick up some broadcast signal independent of the computer. If the TV speakers are used for the computer sound, and the effect occurs with no HDMI cable connected, then the cause is in the TV not the computer. Again, it is possible for electronics to pick up some nearby broadcast signal or similar, even from something like a close neighbor's faulty equipment.

It is a desktop, the only speaker is the TV speaker and the music plays even when the TV is switched off. There is always a small PC speaker inside.(which was used in the old XT days)
There no other speakers of any kind. The music is the same march, nothing else.. I live in a detached house, separate from neighbours -two lawyers and a old gentleman all friends.I have a game card Geforce GT670. There is no UPS or any other power source. The ethernet cable is connected to a TPLink ethernet over power line. The powerline goes to the back of the house where the router is.This ethernet cable is disconnected as I said above. There are no speakers in the TPLink. There is a built in wifi in the computer which is of course not working when the ethernet cqable is disconnected and the router at the back of the house is switched off.and disconnected . The only thing I have not done which I just thought of is to move the desktop to another part of the house.

That's why I was seeking clarification of exactly where the sound originates from.

Yes I understand. This is totally weird. Where is the power coming from? The sound cannot be streamed from the router - all plugs are pulled off.
When a TV program is on, the music can come on so we get two sounds TV and music at the same time. When I immediately switched off the TV, only the music remains.The PC speaker is quite moderately loud not like the old XTs etc. All sound sources have been disabled by manage audio.

I still don't know where you are saying the sound is coming from. You say you get the two sounds, but don't say if they are coming from exactly the same place. Then when you mention turning the TV off, you say the PC speaker is not as loud as an old XT type. That's why I asked where exactly the sound appears from.

I am sorry. When I re read my reply, I realised I was not clear. The sound is coming from the PC speaker. It comes on regardless of whether the TV is on. or not which was what I was trying to say..
The sound is much louder than the XT PC speakers I was used to but not as loud as the TV (I am hard of hearing). Made a mess of explaining this.
Once when I ran the suite of anti malware programs it stopped for about a month. Then it came back and repeated re runs of the same but updated virus definitions anti malware did not stop it.
Then I ran the anti malware in safe mode and that stopped it for about another month but came back. Repeated the anti malware suite runs in both safe and ordinary mode did not stop it anymore.
Thanks for your patience.

Thanks. That is interesting. The music is not either of them. When I get back home, I will look further into it. Thank you again
