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.

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.
