Hi Mike,
Welcome to PCHF. We have a terrific team of techs here and I feel sure that we will be able to get your sound back to normal.
First of all have you made sure that all of your updates are current?
Have you installed any new hardware or software lately?
Is this something that occured all of a sudden or gradually over time?
Have you tried both the front and rear jacks if you have both available?
Have you checked your audio settings, and if so, make sure that the balance is set properly.
Do you also have this same situation occur on your desktop speakers?
Looking forward to your reply,
TTFN
LGW
