Ubuntu - Get audio over optical cable

Question

Is it possible to play audio over optical cables in Ubuntu?

I've got a motherboard with Realtek ALC888 onboard audio. Ubuntu can play music/sounds just fine to my headphones or over analog cables to my speakers.

However, my problem is that I use an optical cable for my speakers (Logitech Z-5500). This works great when I am booted into windows, but so far I have been unable to get it working over the optical cable.

Is there any way to solve this problem?

You have to enable three settings to get it to work:

Make IEC958 output captured from PCM.

Make IEC958 the new default PCM output:

Raise the volume, unmute and enjoy!

All those options will be available if driver has support for it and you have those options enabled under volume control.

Please can you describe where to set those 3 options.
