I don't have ALC880 hardware - all my work has been done with the ALC260.
My ability to answer your question is therefore somewhat diminished.

I really don't know.  I know there's been a lot of work done on the ALC880
support code in recent months but whether that includes SPDIF functionality
isn't something I can answer with any certainty.  I'll try to give some
broad comments though.

This suggests there is only one playback device, and that would be the
analog interface.  Therefore by default at least it doesn't appear the
SPDIF interface is made available.

Are you using any options when loading the ALSA modules or do you just
go with the defaults?

I'll forward your email onto the ALSA developers mailing list for wider
viewing.  That way you may get some thoughts from the developers actually
working on ALC880 code.

S/PDIF support for Intel HDA Realtek ALC880?

[Jonathan Woithe]

I am forwarding the following message I received privately to the list
for others to comment on.  I am not an ALC880 expert and so my ability to
assist is greatly diminished.

No options and I am using a regular kernel. Any suggestions
what options I might add?

Re: S/PDIF support for Intel HDA Realtek ALC880?

[Tobin Davis]

It's possible that your board has been incorrectly configured as a 6
stack w/o spdif.  Here's a simple experiment:  Try loading the sound
drivers with "model=6stack-digout".  If that fixes the SPDIF output,
then great.

Also, to verify that your board is supported, could you submit the pci
subsystem ID?  Use lspci to determine what device the soundcard is, then
lspci -s <pci-id> -vn (where <pci-id> would be the pci device id, i.e.
0:1b).

Re: S/PDIF support for Intel HDA Realtek ALC880?

[Peter Carlsson]

Hello Tobin!

Could you please tell me where to put the "model=6stack-digout" option?
On a Debian system I believe it is the /etc/init.d/alsasound script that
takes care of starting/stopping the sound drivers.

htpc:/home/mythtv# head -n 4 /etc/init.d/alsasound 
#!/bin/bash
#
# alsasound     This shell script takes care of starting and stopping
#               the ALSA sound driver.

Re: S/PDIF support for Intel HDA Realtek ALC880?

there is a directory named /etc/modprobe.conf with the following

-rw-r--r-- 1    61 2006-04-22 14:54 sound

The sound file contains what you told me to look for.

htpc:/etc/modprobe.d# cat sound 
alias snd-card-0 snd-hda-intel
options snd-hda-intel index=0

After modifying this file as suggested I get:

What entries do I have to put in the ~/.asoundrc file?

I am not able to test if all this works until I get home. But it
surely looks very promising indeed.

Thanks for all the wonderful help!

Yes, you got it. This looks like SUSE Linux.
To add it to the file of sound was right.

What entries do I have to put in the ~/.asoundrc file?

I am not able to test if all this works until I get home. But it
surely looks very promising indeed.

Thanks for all the wonderful help!

Best regards,

None.  .asoundrc is NOT required to make sound work.

Hello again!

Just wanted to say that everything works perfectly now,
although I haven't tested with AC3/DTS yet.

Thanks again to all who helped me with this!

Best regards,
Peter Carlsson
