I have a 2 week old HP Pavilion laptop that's great with one major exception...
The audio through headphones is terrible!
There is a lot of interference sound, humming and crackling, like static noise, which is there all the time and fluctuates as the PC is used. It's pitch changes slightly when I use the touchscreen or press buttons.
The sound issue is there with headphones of all quality and doesn't matter whether the power is in or not!
From what i can see the laptop uses HD Realtek Audio, the driver says 'ip to date'
Please help me, I listen to loads of music and movies via headphone and this is driving me crazy!
