<p>Hello,</p>
<p>maybe you don't have the alsa config for pulseaudio. Normally
aplay -L<br>
shows that the default device points to pulse:</p>
<p>null<br>
Discard all samples (playback) or generate zero samples
(capture)<br>
default<br>
Playback/recording through the PulseAudio sound server<br>
</p>
<p>...</p>
<p>pulse<br>
PulseAudio Sound Server<br>
</p>
<p>...<br>
</p>
<p>I guess the Moode audio player tries to access the ALSA device
directly<br>
and fails because the device is already in use by pulseaudio.
There might<br>
also be a configuration option in the player to make it use pulse.
<br>
</p>
<p>Regards<br>
Georg<br>

<div>Hi Mark,</div>
<div><br>
</div>
<div>Thank you for the reply. paplay also works but
there's no change. It's not the playing of the song
that locks up the device and causes Moode audio not
to be able to use it, it's the starting of ledfx.
Once I do systemctl start ledfx the moode audio
player can no longer use the output device
regardless if I play a sound file with aplay, paplay
or don't play a sound file at all. Moode audio can't
use the device until I do systemctl stop ledfx.</div>

<div>Can you use paplay instead?</div>
<div>That is the pulseaudio aplay drop-in
replacement.</div>
<div>I'm guessing you won't have "device or
resource busy" errors when using paplay.</div>

<div>I did not test this! But do let us know if it
works for you :)</div>

<p>I have a Raspberry Pi 3b with a
Hifiberry Amp4/DAC hat runs Moode Audio
OS.</p>
<p>If I pick <code>Pulse</code> as they
audio device in LedFx and play a sound
file with <code>aplay sound_file.wav</code>
my leds react to the music.</p>
<p>The problem is that after <code>aplay</code>
has finished playing the sound file if I
then go try to use Moode audio player
Moode audio won't play music and gives
me the following error:</p>
<p><code>MPD error Failed to open "ALSA
Default" (alsa); Failed to open ALSA
device "_audioout": Device or resource
busy</code></p>
<p>This persists until I stop Ledfx. Is
there a way I can switch back and forth
between aplay and Moode Audio player
without having to stop and start Ledfx?
I am not looking to get LedFx working
with Moode I only want reactive lights
when I play a song with <code>aplay</code>.</p>
