Sound Blaster Recon3Di S/PDIF No Output

Greetings,

I've installed Fedora Linux (with pipewire) on my friend's Alienware M17xR4 (linux-hardware probe).

This incredible laptop got a Sound Blaster Recon3Di with a S/PDIF Digital Output which unfortunally does not work out of the box. I can see the vu meter moving inside gnome-control-center but no audio comes out and the port's red light (which on Windows lights up) does not turn on at all.

By lookin up I've found this thread on Linux Mint Forums but I had no luck with it.

Has anyone else got issues with similar hardware? Thanks in advance.

Are you using pipewire?

Install pavucontrol, what profiles can you see there for this card? I had to change the profile there to get digital output.

Does your red light turn on? I've already tried some profiles there, should double check then.

I don't have this exact card, but used several different pcie soundcards with linux with toslink, and usually I had to fiddle with pavucontrol

Install pavucontrol and go to the Configuration tab in the app. Then check your available profiles. See if one of the default available ones is set for digital out or similar. Just plug something into the output port you know works, play some kind of audio, and click through each of them (you may need to wait many seconds for the switch to happen) to see if one ends up working.

Digital output for IEC958 is going to be the one that works. Reboot if needed.

There's a lot of variables at play here. The simplest thing you can do is compare your sound system profiles and configs and see how they differ. If the setups are similar, you could just take all the configs from PopOs and drop them into your Fedora install I guess.

In addition to the pavucontrol advice, I recommend firing up alsamixer to check the mute and volume of the detected cards and channels.

By selecting "HDA Intel PCH" card with F6, this is what I see:

The S/PDIF isn't muted but its level isn't shown (like is shown for Master and PCM). Could this because of profile in use from pavucontrol or is it something related to alsamixer?

Maybe try unmuting that spdif d... Channel? Seems suspicious

By unmuting "HP/Speaker" the light turns on finally.
By unmuting "HP/Speaker Auto Detect" too, the light turns off again.

As soon as I can, I will try to play something thru it and will report.

Ty!

Edit:
While the light is on, audio still does not come out.
Maybe I should try now to change profile on pavucontrol.
I'll take a look.

Just tried PopOS live and it works out of the box, but I would like to understand why and fix it on Fedora.

Take a look at my other comment for screenshots.
