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.

    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.

    Here's pavucontrol

    Here's alsamixer

    alsamixer sound cards

    alsamixer HDA Intel PCH levels

    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?

      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.
