It's OK, it is easier to check for me as well.

No, it's ok.

Hmm. Maybe this is a problem with your card or the kernel. Please try
the following command:

pasuspender --  speaker-test -D $cardname -c 2

Where $cardname is the name of your onboard chip. You can find it
using `aplay -L`. In my case, the name for the speakers and heaphone
on the laptop is front:CARD=PCH,DEV=0 . Yours may be the same.

That program should alternate noise between the right and left
channels. You can try it without heaphones to check that it works on
the laptop speakers, and then retry it with the headphones plugged in.

If this doesn't make a sound then it is either a problem with your
kernel, the card, or the headphones.
