Sound stopped working today.

TOday I turned my computer on and it has no sound output, I tested my headset with my cellphone and it is working perfectly. Last time I used it, sound was working as expected.

Here are some info:

I can provide more information if needed.

Everything is unmuted in alsamixer, i checked the connection (My headset is connected to the right jack in motherboard).
I really hope this is not a hardware problem.

Could someone help me??

Gratefull,
Heitor.
