Locks up audio stream about pivumeter HOT 2 CLOSED

Here's the asound.conf that setup.sh built for me:

pcm.!default {
type plug
slave.pcm {
type meter
slave.pcm "softvol"
scopes.0 pivumeter
}
}

ctl.!default {
type hw
card 0
}

pcm.dmixer {
type dmix
ipc_key 1024
ipc_perm 0666
slave.pcm 'hw:0,0'
slave {
period_time 0
period_size 1024
buffer_size 8192
}
bindings {
0 0
1 1
}
}

ctl.dmixer {
type hw
card 0
}

pcm.softvol {
type softvol
slave.pcm "dmixer"
control {
name "PCM"
card 0
}
}

pcm_scope.pivumeter {
type pivumeter
decay_ms 500
peak_ms 400
brightness 128
output_device blinkt
}

pcm_scope_type.pivumeter {
lib /usr/local/lib/libpivumeter.so
}

pcm.pivumeter {
type meter
slave.pcm 'hw:0,0'
scopes.0 pivumeter
}

pcm.dsp0 pivumeter

from pivumeter.

I believe this is related to: pimoroni/speaker-phat#13 but I'm not sure.

Trying without the dmixer might work, I think you need to change softvol to type plug and use slave.pcm "hw:0,0"
