With DVD playback finally fixed, I can finally watch movies on. However, one thing leads to another and as soon as I started doing this, I noticed that the volume was awfully low. I turned up the volume everywhere as much as I could and looked around a bit and I suddenly realized that I should have dug a little deeper in the volume settings.
If you right-click on the volume icon on the top bar and select Open Volume Control, you can specifically change the volume of your front speakers. Mine were not turned up all the way and once they were, everything sounded much better.
So, if you have sound problems, check the front speaker sound volume.
