Re: Poor quality audio from PC. What gives?

I bought the termination cap as cybepine suggested and capped an unused Radio coax socket in the wall. (Pictures attached below)
So there's been a development:
The extension cord improvement's effects are almost completely negated when I close the window in my kitchen.
I came to this realization when I noticed that the audio sounded oddly poor even after all the "improvements" I had in place. Turns out, I had closed the kitchen's window the day before. The window has been constantly open for the past 6+ months and I closed it yesterday for the first time since because it's getting chilly. I opened the window again and the clarity is back to before, just like that. It is that bad.
Do I start wearing a jacket inside and have increased audio clarity, or do I close the window and lose audio clarity? This is laughable.
When there is an unobstructed line of sight outside, the opened window must act a quick way out for the interference. Even glass panes seem to trap it inside. This is just what makes the most realistic sense in my head.
I don't know if there is a connection here, but there is another set of 2 water pipes and grounded radiator in the kitchen too, identical to the ones in the living room, just shorter. The openable kitchen window is 10cm above the radiator.
The termination cap helps with the audio clarity and the interference is definitely reduced, but doesn't completely get rid of it.
I still notice the increase and decrease in audio clarity/focus when I plug my headphones into my phone, listen to music and walk back and forth in my apartment. The audio doesn't sound as muddy anymore even when I stand in the TV coax outlet and radiator corner in my living room where it has always sounded the worst. It almost starts to feel like the effect of the interference is halved.
Okay. So I had the foresight to buy 2 termination caps, so I capped both the TV and Radio sockets, and the interference seemed to stop altogether when I had my headphones plugged to the phone. It was very hard to notice any changes in audio clarity, either in the worst spot in the living room or at the apartment's front door where the audio has sounded the clearest.
When I capped the Radio socket, it took the same 15-20 minutes for the clarity to be as strong as possible/settle, just like with the extension cords. There's almost a ripple; the audio clarity goes worse, good, bad, then suddenly very good, then worse, then balanced where it settles. It's all subtle and very gradual.
Once I took the TV socket's cap off and plugged the coax splitter back into it, the interference came back, but to the level as it was after I had capped the Radio socket.
The TV socket is radiating something even with the high quality coax splitter plugged into it.
With that, I'll order the MoCA filter next and hope that it will be the ultimate fix to this. Otherwise, I'll fucking explode.
