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.

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

MrSoup OP ,

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?

mvirts ,

Maybe try unmuting that spdif d… Channel? Seems suspicious

MrSoup OP , (edited )

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.

MrSoup OP ,

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.

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.

MrSoup OP , (edited )

I’ve already tried some profiles there, should double check.

I’ve tried ALL of them and none work.

Might it need a kernel module? I don’t see “Sound Blaster” inside the probe and connector red light does not turn on at all.

just_another_person ,

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

MrSoup OP ,

I’ve tried every profile there and none is working.
So I moved to a live PopOS where it works without doing anything and from the hardware probe the only difference on audio seems to be the Nvidia GK107 HDMI Audio Controller not present.

Refer to my other comment for alsamixer levels on Fedora.

I would like to use Fedora and make it work there. So why does it work out of the box on PopOS?

just_another_person ,

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.

infeeeee ,

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.

MrSoup OP ,

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

infeeeee ,

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

MrSoup OP ,

Please see my reply to @just_another_person (lemmy.zip/comment/11862806)

Gingerino ,

Ooo man!! I have the same problem. My PC it’s the same Alienware M17rx4 and have the Digital optical output S/PDIF on Sounblaster,but dont work! Red light Is off and audio mute.

Please Fix the audio problem on Fedora 40🔧🪛🔩
