Hello, today I received an SMSL PL150 CD player and I connected it to the WIIM Amp Ultra via optical cable, and even though I have the automatic optical playback option active, it doesn't play. I have to manually switch it to that mode. It's worth noting that I have the automatic HDMI option disabled. What could that be?
 
I don't have an Ultra, but I thought it was input switch auto sense rather than an auto play per se, but I may be wrong.

Hi
Auto switching from HDMI to Optical input is not possible.
Either switch the input back to Wi-Fi (using a preset) before turning off the WiiM, or switch the input using a preset.

No es posible cambiar automáticamente de entrada HDMI a entrada óptica.
Vuelva a cambiar la entrada a Wi-Fi (usando un ajuste preestablecido) antes de apagar el WiiM, o cambie la entrada usando un ajuste preestablecido.
I don't use the HDMI input, I read if I'm not mistaken that if both the HDMI and Optical inputs were active the optical one wouldn't work, but I only have the optical one active, I don't want to set the optical input with a preset on the control, since I have all four presets occupied, I have to go into the wiim home app and manually set the optical input, I thought that for example being on the wifi input and turning on the CD player it would automatically switch to optical, but no.

Auto switching from Wi-Fi input to Optical input should work correctly. However, if music is playing over Wi-Fi, you will need to stop and then play a CD (or turn on the CD player). Can you please check.

Did you know that the preset button on the WiiM remote supports 8 presets? Double-clicking on preset 1 activates preset 5. Similarly, double-clicking on preset 4 will activate preset 8.
