Do you have the auxiliary cable plugged into the back IO on the motherboard or the front io on the case? More times than not front IO isn't very good and has a lot of electrical interference causing the bad sound. The audio connector on your motherboard is the green jack.

If the noise is distortion it could be because the volume on the PC is too high for the TV.
If the noise is hiss it could be because the volume on the PC is too low for the TV.
If the noise is a buzz or hum it could be a ground loop between the PC and TV. A ground loop isolator

could help.
You could try a 3 to 2 ac ground lifter on the TV to see if that helps
