DAC/ncmpcpp Audio Issue

Hello all,

Strange issue with my usb DAC and mpd/ncmpcpp. I was having an issue with the DAC not working after being unplugged, read around on this forum to find that unplugging and replugging in was solving the issue for some. After a few times it worked, however now I can not hear any audio coming from mpd/ncmpcpp through the DAC, further more running speaker-check does not work either. When I plug headphones into the PC itself both of these work fine. I CAN hear through the DAC when playing videos through brave and visiting websites, but can not hear them when plugged into the PC. Tried restart MPD process through systemctl, I can ID the DAC in alsamixer, no idea why brave will only play through the DAC and other sounds will only play directly from the PC. Any help would be greatly appreciated!

MPD config file

music_directory "/home/christopher/Music"
playlist_directory "/home/christopher/Music"
db_file "/home/christopher/.mpd/mpd.db"
log_file "/home/christopher/.mpd/mpd.log"
pid_file "/home/christopher/.mpd/mpd.pid"
state_file "/home/christopher/.mpd/mpdstate"

audio_output {
        type                    "alsa"
        name                    "MPD ALSA"
        mixer_type              "software"
        mixer_device            "default"
        mixer_control           "PCM"
}

bind_to_address "127.0.0.1"
port "6601"

Re: DAC/ncmpcpp Audio Issue

Welcome to the boards

Are you sure you are using ALSA for these other "working" usecases?  What is your default device? Do you have relevant config that explicitly selects the DAC? What's your output for

aplay -lL
sudo fuser -v /dev/snd/*

during this situation (i.e. MPD not having any sound, but brave playing back at the same time?
