hi, i am running fedora-11 live-usb 64-bit on an hp elitebook 6930p and for some odd reason the builtin speakers don't work. i can hear sound if i plug-in headphones (even a usb-powered head-set works) but not the built-in speakers (they work under windows).i played around with every option in the 'sound preferences' applet but nothing seems to work (it definitely isnt muted).
i ran alsamixer and master and captur are set to 100.
whats weird is when i hit the speaker unmute button on the laptop case i hear a low "pop" from the speakers.
has anyone got the speakers to work on this laptop ?

some times the mute check box gets checked

it might be the pcm control
see : System / Preferences / Advanced Volume Control
or System / Preferences / Control Centre / Advanced Volume Control

thanks, i tried toggling those switches as well but nothing worked.

well fedora has had sound issues since fedora 8 so...
but your description is almost always that something is muted.
