I'm hoping someone can help me with a problem that is driving me crazy, My PC has been suffering from sound distortion for about 2 months.

Basically, if I am watching a video on youtube (or listening to any audio via my pc) the sound starts crackling and completely distorts after a short while, it sounds kind of like a bitcrusher effect. I have made a video that shows the problem and i will attach it to this post.

The problems started after I decided to clean and update my PC, at that time I updated my chipset drivers, made some edits to the registry, installed new audio drivers, also i had a nasty virus attack. I am unsure which, if any of these would be the cause of the problem. Everything was working perfectly a few months ago. :(

This problem also occurs when i am listening to music via any media player. The only workaround I have when the sound starts to break up is to turn my speakers off and on under "playback devices", this fixes the problem for a shot while before the problem comes back again. (this can be seen in the attached video @ 2:35)

My Specs:

Asus P7H55-M PRO Motherboard
MOTHERBOARD Chipset Intel H55
3 Port Firewire Card - Texas Instruments Chipset 1394a (TI Chipset) (i installed this myself)
1TB Seagate HD
Windows 7 Home Basic, service pack 1
x64-based PC
6GB Kingston DDR3 Ram
ATI Radeon HD 5450

I use the firewire card for my saffire pro 14 soundcard

Things I have tried to fix the problem:

Uninstalling and reinstalling the latest drivers
Disabled CPU Throttling
Uninstalled and reinstalled flash player
Downloaded and used Latencymon & DCP Latency checker
changing power management to High performance.
Disabled onboard sound
disabled unused stuff in device manager
disabled all unnecessary startup progs
changed firewire PCI slot

Can anyone help / suggest what the problem might be?

Have you tried using onboard sound to see if the problem still occurs?
