Here's my related experience (and solution!) with Ubuntu Jaunty and an HDA-Intel card on an HP DV5-1125ca (AMD processor) laptop.
Sound output was working, but I was not able to use the microphone, neither with sound recorder, Skype, or Cheese. Solution in my case was to add this line to /etc/modprobe.d/alsa-base.conf and reboot after: options snd-hda-intel model=hp-dv5 (if you're on an HP DV4, this line might work: options snd-hda-intel model=model=hp-m4) See this thread for more info: http://bugzilla.kernel.org/show_bug.cgi?id=12440 ** Bug watch added: Linux Kernel Bug Tracker #12440 http://bugzilla.kernel.org/show_bug.cgi?id=12440 -- [Jaunty] HDA-Intel - no sound https://bugs.launchpad.net/bugs/316125 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
