You still do not have enough free storage space on the C: drive I`m afraid we are fighting a losing battle until the correct amount of space is freed, we are effectively trying to fix one thing when we know for sure that something else is broken.
But atm there are no headphones connected, is this correct.
Just checking but you say "via a HDMI Cable to the HDMI Port on the back of my PC" is the HDMI cable connected to the add on video card and not to the motherboard.
Have you ever downloaded the latest BIOS for your video card.
Have you noticed in Speccy that your Samsung TV is detected and that your default audio device is now shown as - Audio - Realtek High Definition Audio, no mention of AMD which if you should have if the correct drivers are installed and you are connected to the HDMI port on the R9 video card.
Will take me a while to get through the drivers list but will get back to you shortly.
EDIT: Yeah, sorry, the Windows Update used a lot of space, I'll clear up more now.
Correct, only Audio Capable device is my TV, that with the headphones is just something I saw yesterday which was strange, since as I said, before all this happened it was shown normally as headphones, not speakers in Playback (Manage Audio Devices).
I don't quite get what you mean "is the HDMI cable connected to the add on video card and not to the motherboard.", is that a question or a statement? I am not sure, I only ever connected my TV this way. It's a slot on the back of my PC for HDMI, right next to the slot for Displayport. There is no other HDMI slot/port on my PC.
Yes, I know that my Samsung TV itself is detected, as well as the TV as a Monitor, it's just not shown anywhere as an Audio Device, something it was before all this happened.
I'll upload some screenshots to show you what I mean.
