View Full Version : [ubuntu] Alsa and SPDIF on Gibabyte mb

April 29th, 2010, 04:03 PM

I own a motherboard P55-ud3r from Gigabyte.
And installed the SPDIF-IN connector (to record digital input).

(this is my sound profile (http://www.alsa-project.org/db/?f=ccf5a27b1089c7b12b58da06695417d2181694ad))

The SPDIF-IN (nor OUT) is not seen by Ubuntu (alsamixer shows IEC958 as off but it can be enabled - if that matters)

What is the way to get the drivers to see SPDIF IN?

Thank you.

Have you tried using alsamixer? Terminal="Applications->Accessories->Terminal"


Press F5 for all elements (or <tab> over). Scroll right with arrow keys. Look for spdif, or 'input source', probably better. Toggle the source input options with up/down keys. Also have a look at gnome-alsamixer and make sure all options are enabled in 'Edit>Soundcard Properties'. Check all the options/levels etc. If not installed:

sudo apt-get install gnome-alsamixer

Dear lidex, thank you for your answer.

I know alsamixer for a long time, and - as I said in the 1st post - used it to enable iec958.

But it seems the input cannot be seen - this is a direct laser input S/PDIF.

Any other comment will be welcome
