By JACK server, I mean jack audio connection kit. I want to share speakers with Raspberry Pi 3 B+ and a desktop computer.
Desktop computer's onboard SPDIF out ==> I2S SPDIF in --> JACK server --> I2S SPDIF out --> SPDIF in on SMSL AD18 Amplifier --> Speakers
Raspberry Pi 3 B+ plays its own sound by executing JACK clients that connect to JACK server.
Does this setup cause any pops, clicks, or xruns? I read that SPDIF have jitters that can lead to pops, clicks, and xruns.
