After wrestling all day with an ASUS Xonar SE card (with accompanying Googling), I now believe that this card cannot be made to work in Linux. Stereo output through the green line out port works fine, but SPDIF does not. "lspci" actually claims this thing is a USB controller, although as I mentioned stereo sound does work.
Does anybody have a PCIe sound card that is known to work with SPDIF 5.1 surround sound output? It has to be optical as those are the only digital ports on my receiver.
One frustrating thing about trying to search for information online is that I come up with a lot of stuff that is way too old to be useful. For instance, a lot of the advice articles I found on getting sound working mention 4Front and OSS sound drivers, which is probably 15-20 year old information. I'm looking for first hand "yes I know this card works", or at least a pointer to something that isn't Ubuntu specific and is recent enough to be useful.
Thanks, --Greg

More details about what "doesn't work" means would be helpful. Do you see a SPDIF option in the sound output settings?

That is really old information. Probably the reason it's hard to find anything more recent is because generally it all just works.
Thanks for answering.

In "pavucontrol", it actually does have a listing for the Xonar Sound Card, but only the analog output port is available. In alsamixer, I can press F6 to select sound card, and "Xonar Sound Card" is a selection, but there is no iec958 device.

But it actually is a PCIe x1 card.
If I get into the audio settings in MythTV, it will show the iec958 device, but setting the audio to use it produces no sound.

That's true for stereo sound, but not so true when you try to use surround sound and iec958 devices.

Audio, bluetooth, and other I/O is often implemented using USB devices, so it should not be surprising to find a USB controller. You should be able to find the USB id's. According to ASUS ( https://www.asus.com/Sound-Cards/Xonar-SE/specifications/), the card uses a "C-Media USB2.0 6620A High-Definition Sound Processor (Max. 192KHz/24bit)".
https://www.audioshark.org/ might be able to help -- there are linux users doing serious audio work.

It could possibly be one of these. The output from "aplay -L" would be useful. Also, "pactl list cards" and "amixer -c0 scontrols".
Which specific Xonar model do you have?

I expect this is the card.

But it actually is a PCIe x1 card.
What they've done is combine a USB audio chipset and a PCI USB controller on a single card.
If I get into the audio settings in MythTV, it will show the iec958 device, but setting the audio to use it produces no sound.

The card is an ASUS Xonar SE
I also found alsa.opensrc.org that has some helpful stuff, especially the DigitalOut section, but it's going to take me a while to understand all of it.
So "aplay -L" does actually show an iec958 device; MythTV had to be getting it from somewhere. This gives me some hope that it might be possible to eventually make this card work.

Add "-vv" or "-vvv" to the command to be able to tell if it's actually sending something. Also, try this command with "DEV=1" as well. If you still don't hear anything, then run alsamixer and turn up all of those PCM outputs and try both of them again.
It's strange that pulseaudio and ALSA know about the digital output, but you can't select it. Something that I should have asked earlier though is whether or not the optical cable is lit up.

I wanted to use "cset ... unmute", because the iec958 device seems to be muted by default sometimes, but I couldn't figure out how to specify that control. The amixer man page says:
cset <CONTROL> <PARAMETER> ... Sets the card control contents. The identifier has these compo‐ nents: iface, name, index, device, subdevice, numid. The next argument specifies the value of control.
...but I couldn't figure out correct values for all these components. My attempts always got:
[mythtv@seveneves ~]$ amixer cset numid=19,iface=CARD,name='IEC958 In - Output Jack' unmute amixer: Cannot find the given element from control default
$ aplay -D iec958:CARD=SoundCard,DEV=0
Add "-vv" or "-vvv" to the command to be able to tell if it's actually sending something. Also, try this command with "DEV=1" as well.
Using DEV=1, I get:
[mythtv@seveneves ~]$ aplay -vv -D iec958:CARD=SoundCard,DEV=1 /pub/flac/music/rock/CDs/Country_Joe/CollectedCountryJoe/CCJatFT05.wav aplay: main:830: audio open error: No such file or directory
Using -vv on the DEV=0 version does show the "meter" with the pound signs bouncing up and down, so it thinks it's sending something. But the optical cable is not lit. I did check the obvious and the stupid, and it does appear to be fully seated into the card. While I was at it, I also tried using a different optical cable that I know is good, but still no sound.
If you
still don't hear anything, then run alsamixer and turn up all of those PCM outputs and try both of them again.
Turning them all up in alsamixer was the first thing I tried. They are all maxed out.
It's strange that pulseaudio and ALSA know about the digital output, but you can't select it.
That is not an encouraging sign, but I have learned more about how this stuff works from this conversation than I ever knew before, so there is a lot I don't know.
Something that I should have asked earlier though is whether or not the optical cable is lit up.
Funny, I thought of this as I was going to sleep last night. I guess it's evidence that I spent too much time on this yesterday and got too frustrated; my brain was not working very well. I should have thought of that much earlier.

There has been a completely new development in this saga. One thing I had also been investigating was to see if I could somehow get surround sound through the onboard Intel sound chip. This chip does not have a iec958 (optical) device however, so it wasn't going to work directly with my receiver. As a temporary workaround I was attempting to at least get stereo sound going through the line out of this chip, and it was not working, despite the fact that it worked fine on another machine in the house with an identical motherboard. Then I remembered that the UEFI has settings for the onboard devices, and by default the onboard audio is set to "Auto", which it turns out means Enabled unless there is a sound card installed. So that's why it didn't work on the machine with the Xonar card installed. I changed it to Enabled and I got stereo sound. I can also now see four separate HDMI sound devices in aplay. So I played around with some of the things I have learned recently, and it turns out that this chip can do surround sound via HDMI, and since the TV that the system is hooked up to can pass that on to the receiver, I decided to try it, and it mostly works. I say "mostly" because when I run the 5.1 surround sound test in MythTV, it does front left, center, front right just fine, but "surround right" means both rear speakers at reduced volume, and "surround left" means both rear speakers at normal volume. That's of course not how surround sound is supposed to work, so I still have a few things to look into there (including things like settings on the TV).
So I'm still interested in trying to get the iec958 device on the Xonar card to work, because I expect I'd get better quality sound that way, but the urgency is reduced.

That's promising. Try: amixer -c0 sset 'IEC958 In - Output Jack' on Now that you've enabled the onboard sound card, it might have changed the numbering, so if that gives an error, try "-c1" instead. Hopefully, the optical port lights up after that.
