Okay so...its currently Feb, 15th 2022. Just got myself one of this O2+SDAC Dac/Amp but still just like everyone else...no audio. The only way i actually seem to be able to use it, is by the RCA cables to my older amp (FX-Audio Amp) but the volume is extremely low and i cant adjust it on the 02 amp...what a waste of money lmao.
