From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Sound Blaster Recon3Di S/PDIF No Output (self.linux)

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.

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.

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.

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

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

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.
