I have notebook HP NC4200. I report an issue that when I plug my headphones to the notebook, I hear sound from headphones and from internal speaker; I assume that internal speaker should be muted. WinXP works OK, so this is not a HW issue.
Ubuntu 10.10, i386
$ lspci | grep -i audio 00:1e.2 Multimedia audio controller: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) AC'97 Audio Controller (rev 03)
$ lspci -n | grep 00:1e.2 00:1e.2 0401: 8086:266e (rev 03)
