Hagen, as per http://us.acer.com/ac/en/US/content/drivers an update is available for your BIOS (1.41). If you update to this, does it change anything?
If not, could you please both specify what happened, and provide the output of the following terminal command: sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. Thank you for your understanding. ** Tags added: bios-outdated-v1.41 ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1051947 Title: Acer TravelMate 6293 - no s/pdif (iec958) anymore since Ubuntu 12.04 LTS Status in “linux” package in Ubuntu: Incomplete Bug description: Since upgrading to Precise the IEC958 setting is missing when opening 'alsamixer', resulting in no S/PDIF output signal at all. Prior to that, it was possible to add the ALC267/268 module option "snd-hda-intel model=zepto" to forcible activate the S/PDIF support, but this parameter has been vanished with kernel version 3.2.x. When installing a 3.0.x kernel (from Ubuntu 11.10) it works again. --- ApportVersion: 2.12.1-0ubuntu2 Architecture: i386 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: ubuntu 2704 F.... pulseaudio ubuntu 4506 F.... pulseaudio CasperVersion: 1.336 DistroRelease: Ubuntu 13.10 LiveMediaBuild: Ubuntu 13.10 "Saucy Salamander" - Alpha i386 (20130829) MachineType: Acer TravelMate 6293 MarkForUpload: True Package: linux (not installed) PccardctlIdent: Socket 0: no product info available PccardctlStatus: Socket 0: no card ProcEnviron: LANGUAGE=de_DE TERM=xterm PATH=(custom, no user) LANG=de_DE.UTF-8 SHELL=/bin/bash ProcFB: 0 inteldrmfb ProcKernelCmdLine: noprompt cdrom-detect/try-usb=true file=/cdrom/preseed/hostname.seed boot=casper initrd=/casper/initrd.lz quiet splash -- maybe-ubiquity ProcVersionSignature: Ubuntu 3.11.0-4.9-generic 3.11.0-rc7 PulseList: Error: command ['pacmd', 'list'] failed with exit code 1: Home directory not accessible: Permission denied No PulseAudio daemon running, or not running as session daemon.
