i've got a similar/the same problem on an HP compaq 615
i had a problem with my audio quitting on me after the laptop went to sleep (which required a reboot) so i reinstalled the drivers
now my laptop speakers are set as the default audio device and my headphone jack is set as the default communications device .. what kind of nonsense is that..
anywho.. all efforts trying to tell the pc i want the headphones as default speakers were in vain... it won't change any settings
simply disabling the speakers isn't a real solution either because i would still like to be able to use the media keys on my keyboard to adjust the volume.. i can't use them on a device that isn't the default however
i tried reinstalling the drivers aswell with no results
any ideas what i could do about this?
