[gentoo-user] Intel High Definition on-board sound controller - optical out working?
I have an optical out on my on-board Intel Hi Def audio controller (also an Intel motherboard) and wanted to route the optical output to my receiver, so I could play internet radio on my home audio system. I got everything plugged in, but the receiver didn't pick up any signal (I made sure all the right settings are selected on the receiver). So my question... Is optical output supported in ALSA and the driver for Intel High Definition audio controller? Do I have to compile with any specific flags to get it working?

Check the file /usr/src/linux/Documentation/sound/alsa/HD-Audio-Models.txt and maybe you need to specify which model of HD-Audio chip your're using to enable the extra ports. I've never had much success with auto actually autodetecting the proper set-up.

Also, the digital output may show up as a different playback device in ALSA, so you may need to specify this in whatever program you're using. For example: $ aplay -l List of PLAYBACK Hardware Devices card 0: Intel [HDA Intel], device 0: ALC889 Analog [ALC889 Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: Intel [HDA Intel], device 1: ALC889 Digital [ALC889 Digital] Subdevices: 1/1 Subdevice #0: subdevice #0

I am mostly interested in streaming audio from browser, stuff like Pandora radio and what have you. Otherwise, I use Audacious when I'm not streaming.

I also had: aplay -l List of PLAYBACK Hardware Devices card 0: Intel [HDA Intel], device 0: STAC92xx Analog [STAC92xx Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: Intel [HDA Intel], device 1: STAC92xx Digital [STAC92xx Digital] Subdevices: 1/1 Subdevice #0: subdevice #0 I basically emerged alsa-plugins and went through alsaconfig document again, followed by mixer settings to make certain all channels are unmuted. I looked at the sound card ports, and the optical was lit up red, so I connected it to the receiver, and it works now! Thanks :-)

I never thought I'd use it until I got a receiver that got optical in, and it's a nice solution for routing internet and computer music to home stereo - sounds really good, actually :-) Looks like Gentoo has it together for making use of the digital port without having to doctor any config files or module loading options for Intel HDA, other than emerging alsa-plugins and making sure alsamixer has all the relevant ports unmuted.
