I purchased a DAC+ADC Pro as I need a one stop solution for audio input and output. I was able to get my dynamic microphone working, though there is static when not using the mics push to talk. My main issue/concern is the audio out is not very loud for me. I'm using a small 4 ohm passive speaker that I commonly use, but even with audios I import output isn't really loud enough to hear without bringing the speaker to my ear. Is the hat supposed to be able to drive a passive speaker? and if not is it possible to put a hifiberry amp on top of this DAC+ADC Pro?
