some workaround: I added "options snd_hda_intel model=laptop" to the end of "/etc/modprobe.d/alsa-base.conf"
After each reboot execute: killall pulseaudio sudo alsa force-reload If problem with microphone: install some alsamixer and adjust microphone In my case microphone didn't work before adjustments.... -- No sound after karmic upgrade & hda-intel warnings https://bugs.launchpad.net/bugs/421250 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
