Greetings,
I'm trying to understand your problem description.
Output:
Are you using analog or optical out?
Do system sounds play normally?
What port(s) are your speakers connected to?
Input:
What are you plugging into the Line-In port? (This is port "K" on the lower right hand corner)
Does "port sense" detect the device when connected?
Display:
Are you connecting to an external display using HDMI?
"I can hear a slight thump when i turn sound up to max on the ports " .. Volume? on what exactly (your speakers)?
"When I check windows sound options it shows the signal it is there and its strong but getting very low and distorted sound from the input"... On the Recording tab, "Line In"?
So you see your input and it's strong? But playback is low and distorted?
