[Bug 1051947] Re: Acer TravelMate 6293 - no s/pdif (iec958) anymore since Ubuntu 12.04 LTS

 

Hagen, could you please confirm this issue exists with the latest
development release of Ubuntu? ISO images are available from
http://cdimage.ubuntu.com/daily-live/current/ . If the issue remains,
could you please run the following command in the development release
from a Terminal (Applications->Accessories->Terminal), as it will
automatically gather and attach updated debug information to this
report:

apport-collect -p linux <replace-with-bug-number>

Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.11-rc4

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

If you are unable to test the mainline kernel, please comment as to why specifically you were unable to test it and add the following tags:
kernel-unable-to-test-upstream
kernel-unable-to-test-upstream-VERSION-NUMBER

Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results. Thank you for your
understanding.

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.
