Hi everyone, I'm not sure if this is the right place for this as i'm new on here, I turned on my comp the other day and i couldn't get my laptop speakers to make any sound, i plugged in ear phones and i can get sound through them just not the main speakers. After mucking around (i cant remember what i did) I managed to get a song to play through itunes, but no other programs. ive turned my laptop on 3 days later to no sound at all not even through itunes. Ive looked through device info and all seems fine, nothing is muted, and i dont know what else to do. The computer is a 13 month old hp pavillion dv7 please help!
