I was having this problem with the same mobo. The workaround in #27 worked for me as a temporary solution.
Problem seems solved after installing Realtek drivers from here: http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=14&PFid=24&Level=4&Conn=3&DownTypeID=3&GetDown=false Tested with version 1.0.25-5.17rc5 (there's rc8 now). No more out of range errors in dmesg for hda-codec. I don't know if this is eventually going into ALSA or even if plain ALSA 1.0.25 is enough for ALC898 to work. I can't test that right now as this is a production machine. alsa-info.sh output is here: http://www.alsa-project.org/db/?f=9dd18f23f2c450918d9342396cd24db7f6781050 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/996245 Title: [Gigabyte MB: GA-Z77X-UD5H-WB, ALC898] No sound from headphone/line- out jacks To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/996245/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
