I had a little trouble with my new laptop, I have a Packard Bell MZ380 laptop with Realtek High Definition Audio, I have installed CentOS 5 on it, I have sound by the speaker but when I plug the headphone the sound is over, I mean I have not sound by the speaker and by the headphones. Can someone help me? What I have to do ???? I'll be waiting for help.
are these analog mini-phone jack headphones, or USB headphones?
If the former, it sounds like it could be a hardware problem to me, maybe a mechanical issue with the headphone jack. are you sure the headphones work on another sound source like a ipod ? are you sure the headphone plug is fully inserted ?
the mini phone jack itself has a mechnical switch in it that opens when you insert a plug, this disconnects/mutes the sound from the speakers.
