I had the same problem and I have solved it completely removing the line options snd-hda-intel model= from /etc/modprobe.d/alsa-base Now everything works: internal and external mic and speakers.
I have 2.6.24-19-generic kernel and alsa-base 1.0.16-0ubuntu4 on x86-64. -- Ubuntu 8.04 mic input in XPS M1330 https://bugs.launchpad.net/bugs/231436 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
