mpd / ncmpcpp clashes with waterfox

[Furycd001]

HI

If I open any media in waterfox (youtube, twitch etc) then I cannot play music though ncmpcpp until I close waterfox. How can I stop this from happening ?? I run mpd as user instead of service. Also I cannot seem to get the visualizer in ncmpcpp to work. Here is my mpd config && ncmpcpp config. Many thanks in advanced for your help....

You have mpd set to use the hardware device (alsa output hw:0,0). If another program is playing sound, then pulseaudio has exclusive access to the hardware device.
In other words, try setting mpd to use pulse output.
