Hello,
I’ve been experiencing an issue with my digital audio output (optical) having delays and popping when switching between audio from different sources. If I, for example, play some music through Spotify and then pause it and immediately play audio through Firefox, there will be a 1-2 second delay as well as a popping sound before the Firefox audio switches. The same occurs in the opposite direction. However, if I am already playing some sound through one of them and turn on the other while it’s playing then there is no delay or popping.
I originally thought that this may be caused by some form of powersaving since I had similar issues before with analog audio and commenting out load-module module-suspend-on-idle fixed it, but I cannot find a similar variable for specifically digital output. When I do try the steps listed above through analog outputs the issue does not occur and the audio switches properly.
My inxi output:

The device that I’m currently using is the ASUSTek Xonar SoundCard type: USB driver: hid-generic,snd-usb-audio,usbhid bus ID: 3-1:2 but I experienced the same issue using the optical audio output in my motherboard.
Any suggestions are appreciated. Thanks.
