I noticed a problem of Matrix Mini i Pro 4. When input source is toslink and the volume is lower than certain level (could be -70db), mini i pro 4 will try to switch off the output immediately, and generating a breaking noise.
My setup is Nintendo Switch -> HDMI to toslink separator -> toslink optical -> mini i pro 4, and also other input sources connecting mini i pro 4. So the mini i pro 4 is not only used for listening music, but also a general DAC connecting all my devices.
When playing games on Nintendo Switch, the above problem is causing a lot of noise, mostly when i open menus in game. The BGM of the game is not playing after opening menu and changing tabs in menu got a "bip" sound, this "bip" is never correctly decoded and I can only hear a lot of "switching input" that kind of noise.
I have tried connecting toslink to Mojo and there is no such problem; also tried connecting toslink to PC, then PC record the sound and use USB connecting to mini i pro 4, also no problem. Only toslink directly connecting to mini i pro 4 got problem.
The same problem happened on mini i pro 3, and Matrix used to fix it by firmware upgrade. Could customer service people help to raise this problem to devs and fix in next firmware update?
