Bug Description

I have an Asus M3N78-VM motherboard with VIA VT1708B onboard sound.

This board has digital sound output via HDMI and a separate optical S/PDIF output jack. However on Intrepid I can only see the analog output device.

Output from aplay -l:

Asus M2N68-VM, no optical audio...no optical light...no HDMI audio either, but just optical would do :)

Gutsy has no driver for the VT1708B, so its task should probably be rejected.

HDMI-Output works on custom-compiled alsa 1.0.18a with aplay -D plug:hdmi test.ac3. But neither on Hardy, Intrepid nor Jaunty Alpha 3 there is light on the optical-out. As far as i can see, there was a BIOS update with broke it. With the original Bios i could select either HDMI or S/PDIF. this switch is gone after an update. And I could imagine that alsa relies on this Information to switch between HDMI and S/PDIF.

Any help to get S/PDIF working would be much appreacheated!

Just FYI regarding latest ALSA releases:

I manually installed ALSA 1.0.19 over Intrepid last night and see analog (which works) and HDMI (which I cannot confirm) but no S/PDIF device under aplay -l. Since my motherboard (an M2N78-VM, same audio device as OP) was bought yesterday I assume it has the latest BIOS. There is indeed no option in the BIOS to switch between HDMI and S/PDIF, only to turn "AZALEA" (the audio hardware) completely off.

I'll post detailed information tonight when I'm in front of the computer in question.

I also have the same problem with optical output with ALSA 1.0.19 on Asus M2N68.

Hanno Stock, thank you for reporting this and helping make Ubuntu better. This bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

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

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

There seems to be a fix for this issue in the 3.13 upstream kernel. commit number c9a6338aecdb92f9d015ecc26d203e54250bebbb - ALSA: hda - hdmi: Fix IEC958 ctl indexes for some simple HDMI devices

This fix has also been ccd to the stable kernel series.
