AC3/DTS Passthrough Not Working

I am running a fully up to date Tumbleweed install. From my desktop, I want to be able to passthrough Dolby Digital/DTS over an optical S/PDIF connection to my receiver for decoding. I have not been able to do this even if I check AC3 and DTS in the Pavucontrol utility.

I have tried everything I can think of, but I haven’t messed with this type of audio hook up in a few years. I know that with Pulse other applications can block passthrough, but even when I close all other applications passthrough doesn’t work.

The only think listed under playback in Pavucontrol is “System Sounds”. Could the KDE system sounds be blocking passthrough and, if so, how can I kill it so I can get passthrough.

Any help is much appreciated. Thank you.

So as is typical, right after I post this I stumble onto the answer. In the Pulseaudio daemon.conf file you have to set the resample rate to 48000, restart Pulse and it will then output the passthrough audio correctly.
