The speakers did not work after installation, and after I fixed it, it would not work after suspend. It turns out some of the flags were not set correctly. I can fix these problems but it would be nice to have them fixed at installation. The problem can be seen in the GPIO section in /proc/asound/card1/codec#0 (card0 is for HDMI). After boot, the GPIO flags for IO[0] were GPIO: io=6, o=2, i=0, unsolicited=1, wake=1 IO[0]: enable=1, dir=1, wake=0, sticky=0, data=0, unsol=0 If data were set to 1, sound would work! I fixed this by installing alsa-tools and adding to /etc/rc.local a line: hda-verb /dev/snd/hwC1D0 0x1 set_gpio_data 1 After resuming from suspend, the GPIO flags for IO[0] became GPIO: io=6, o=2, i=0, unsolicited=1, wake=1 IO[0]: enable=0, dir=0, wake=0, sticky=0, data=0, unsol=0 Here, three flags were set to 0. I fixed this by adding to /etc/pm/sleep.d/99_myfix a few lines: #!/bin/sh case "$1" in resume|thaw) hda-verb /dev/snd/hwC1D0 0x1 set_gpio_mask 1 sleep 1 hda-verb /dev/snd/hwC1D0 0x1 set_gpio_direction 1 sleep 1 hda-verb /dev/snd/hwC1D0 0x1 set_gpio_data 1 ;; esac --- ApportVersion: 2.12.5-0ubuntu2.1 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC1: lic3 3717 F.... pulseaudio /dev/snd/controlC0: lic3 3717 F.... pulseaudio DistroRelease: Ubuntu 13.10 HibernationDevice: RESUME=UUID=a2156b27-f1e5-4408-9fb3-491e6f8229fb InstallationDate: Installed on 2013-11-06 (21 days ago) InstallationMedia: Ubuntu 13.10 "Saucy Salamander" - Release amd64 (20131016.1) MachineType: Apple Inc.
