accesses alsa directly and unfortunately there is no option for

<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>That is the pulseaudio aplay drop-in

<div>I'm guessing you won't have "device

paplay.</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>
