I've just fixed this issue executing this command: sudo bash -c "echo 'options snd-hda-intel model=auto position_fix=0' >> /etc/modprobe.d/alsa-base.conf"
I found this on Ubuntu French forum: http://forum.ubuntu- fr.org/viewtopic.php?id=428181&p=2 Hope this helps. Note: I'm using Ubuntu Natty Alpha 2 with KDE 4.6, and my laptop is Asus N53Jf. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/725877 Title: [Realtek ALC259] No external audio on ASUS N53JF -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
