I'll start off by saying that I've had a few issues in getting the audio to go from the laptop to the TV but after uninstalling and re-installing the drivers a few times I got that to work. Even now though, every time I want to stream to the TV using the HDMI cable, I have to disable and re-enable the High Definition Audio Device (HDMI) Driver. So I don't know if this could be a part of the problem.
So I initially thought that the cracking and popping could be caused because I was streaming video, but this happens when I watch DVDs and when my videos are fully loaded still. So during my testing, I had youtube open and I opened a new tab to find out some information and the cracking / popping stopped while the audio still came through. I switched back to the youtube tab and the cracking / popping immediately returned.
So whenever the video is being displayed there is a popping / crackling noise. But if audio is just being played, there is no popping / crackling. Is the problem my TV, my laptop, or my HDMI cable? And how can I fix it?
My laptop specs are these:
HP Pavilion dv4-1431us Intel(R) Core(TM)2 Duo CPU T6500 @ 2.10GHz 2.10GHz 4.00 GB RAM 32-Bit
