Krovlar: The DVD quality thing did not work. I think I managed to solve the problem though. For anyone interested
I tried updating my Realtek audio drivers from my motherboard manufacturer site, it did nothing. Then I installed the Realtek ones off of their official site, and that seems to have fixed my issue completely. I'll keep this updated if things change.
Updating device drivers to the latest version is something you should always do first when you encounter a device problem. Indeed, even better is that all of your video-card and sound-device drivers should be kept up-to-date on an ongoing basis. Just every now and then you should always check with the web sites of the manufacturers of your hardware!...;) (Only time you maybe can't do that is with laptops which use custom-designed OEM-only hardware, in which case the manufacturer of your laptop may be the *only* place to get device-driver updates.)
Aside from OEM-custom laptops, the manufacturer is *always* the place to check for your on-board device drivers, though. You should update even the core-logic drivers for your motherboard from the *core logic* manufacturer--for instance, if you have an Asus mboard with an Intel core logic chip set you should update your drivers for the chip set from Intel as opposed to Asus; and if it's an AMD chip set mboard by Asus then likewise you update from AMD instead of Asus, etc. (If you have an AMD/ATi 3d-card installed in an AMD core-logic chip set mboard then when you update your Catalysts the core logic drivers are updated to the latest at the same time.)
Really, the only things you must update from the mboard manufacturer are the bios or UEFI updates which are always custom-crafted to your mboard by the motherboard manufacturer and cannot be obtained from any other source.
