local fn = {}
for chunk in io.lines("/disk/music/bo.dfpwm", 16 * 1024) do
    local buffer = decoder(chunk)
    for i, v in ipairs(speakers) do
        fn[i] = function()
            local name = peripheral.getName(v)
            while not v.playAudio(buffer) do
                repeat
                until select(2, os.pullEvent("speaker_audio_empty")) == name
            end
        end
    end
    parallel.waitForAll(table.unpack(fn))
end
