If this is the same bug as the other Touchsmart 300 the headphones jack works but no speaker output the following should fix it. Have you tried adding this line to the file /etc/modprobe.d/alsa-base.conf?
options snd-hda-intel model=mobile -- no sound from sample videos, system, cds or dvd/ Touchsmart 300 w/windows 7 dual boot https://bugs.launchpad.net/bugs/560451 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
