I know that this point has been discussed several time, but after having tried all the proposed solutions without success and re-install a couple of time lubuntu, I really need help from linuxian experts.
the problems :
1) the integrated micro does not work (gmail videochat, guvcview, ...) and I already tried all the possible alsamixer configurations. In some configurations (internal micro I think), I got a kind of background sizzle but nothing sensible to my voice or any external sounds.
2) the integrated speakers work correctly but, when I plug headsets or external speakers there is no sound.
all the info are here :
Thanks for your help
