No, it was set to 0. I set it to 1 and that fixed the issue.
Thanks!
Also, Maurice mentioned "sndioctl -d" so here is the output:
073:input[0].level=0..255 (120)074:input[1].level=0..255
(120)105:input[0].mute=0..1 (0)106:input[1].mute=0..1
(0)009:output[0].level=0..255 (126)010:output[1].level=0..255
(126)041:output[0].mute=0..1 (0)042:output[1].mute=0..1
(0)001:mpv0.level=0..127 (127)000:test0.level=0..127 (127)
