Mac audio problems

Only a slight problem, but it gets annoying quickly. I can adjust my speaker audio from alsamixer in terminal, by using the pcm slider, but whenever I try to adjust using master volume, it doesn’t adjust it. All audio works fine with headphones plugged in, and I can change using master volume. All software is up to date (6/1/2020)

UPDATE:I found a guide explaining how to fix this, and it worked great, for anyone else having this problem with a mac:slight_smile:
