[labibsharar]

my laptop model is alienware m11x r2.I have realtek HD speakers built in.I turned on my laptop today and realized that my right speaker is not working.

THINGS I TRIED:

*I went to realtek HD audio manager and clicked test,like in the screenshot below.When i clicked "test",The test sound of the left speaker came through the left speaker,and also the test sound of the
right speaker also came through the left speaker(A BIT MUFFLED)



*I also checked the balance of speakers.its was balanced.

PLEASE I NEED IMMEDIATE HELP!

Have you tried headset to see if it's the actual speaker or a problem in the PC?
