Mint 9 No sound in new HP Laptop - fresh install

[HaNgoc]

Hello all,

I just bought a new HP 14in laptop yesterday and the first thing I did was install MInt 9 on it. Everything is going well except no sound at all. Not even the 'start up chime' of any music/videos. I have the volume buttons working on the laptop and I have checked sound preferences and nothing is muted.

I did not dig much further as I have learned with mint and ubuntu that can create problems. This is a fresh install and no sound from the get go.

How should I proceed to trouble shoot?

Thank you

forgot to mention that my headphones work once plugged in, but not the lap top speakers.

Thank you

Hi,
could you report sudo lshw -C Multimedia?
and show what sound preferences->Hardware screenshot?
