<p>Hi,</p>
<p>mh, looks like you have a problem then. Pulseaudio exclusively
opens the sound devices, so<br>
if the player cannot be configured to use the alsa default device,
it will not work. You could<br>
try using dmix (<a class="moz-txt-link-freetext" href="https://wiki.archlinux.org/title/PulseAudio">https://wiki.archlinux.org/title/PulseAudio</a>
chapter 5.1.3, just used Google,<br>
did not check the content)<br>
</p>
<p>The only other option left is to start the player with
pasuspender, but then again ledfx won't<br>
work while the player is active.</p>
<p>Regards<br>
Georg<br>
</p>

<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>
<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>
