I’m new to linux. I am not getting sound output using SPDIF and was wondering if anyone might know how to troubleshoot the problem. The SPDIF cable does have a red light going through and when I unplug and plug it back in there’s a notice that says “polaris 22 hdmi audio digital surround 5.1 (hdmi 5)”

Please run inxi -Fazy and pa-info and post the output of both.

inxi -Fazy #it wouldn’t let me post result because no links rule but I didn’t see what link it was referring to?

pa-info #results were so large that I’m not sure how to view the beginning/top again.

Run

cd
pa-info > pa-info.out
curl --upload-file pa-info.out https://aptget.xyz

In the system settings, you can change the default audio output device? What options do you have there?

System Settings - Audio - Devices (tab) - Playback Devices - HDMI . DisplayPort 5 (Polaris 22 HDMI Audio Digital Surround 5.1 (HDMI5))
#Appears to be no way to change Playback Devices

I have the same machine as you. Driver support for I/O is flakey. For instance, I never got HDMI audio working without crackling. Currently have a bluetooth headset for audio.
