Hi,
when you are changing default.pa anyway, you can comment out the lines
loading module-udev-detect and module-detect near the top of the file.
Usually,
module-detect is not loaded anyway. Also, you can load module-alsa-sink and
module-alsa-source at the same place. If you take a look at default.pa,
there are
some examples.
Regards
Georg

Thanks for the idea George. I tried using dmix with the instructions
in the link that you provided above but it instructs to create a .pa
file in the directory: |/etc/pulse/default.pa.d/| but this is a
directory that does not exist on the RPI. I have tried appending the
lines:
|unload-module module-udev-detect unload-module module-detect
load-module module-alsa-sink device=dmix load-module
module-alsa-source device=dsnoop |
to my |/etc/pulse/default.pa <http://default.pa>| but that causes
aplay to give a busy error: |aplay: main:830: audio open error: Device
or resource busy| and Moode to also still give one as well.

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

Hi,
so what's the output of aplay -L?

Hello Georg, Thank you for the reply. Yes Moode accesses
alsa directly and unfortunately there is no option for
making it use pulse.

Hello,
maybe you don't have the alsa config for pulseaudio.
Normally aplay -L
shows that the default device points to pulse:
null
Discard all samples (playback) or generate zero
samples (capture)
default
Playback/recording through the PulseAudio sound server
...
pulse

...
I guess the Moode audio player tries to access the ALSA
device directly
and fails because the device is already in use by
pulseaudio. There might
also be a configuration option in the player to make it
use pulse.

Yes it's a requirement. Setting the audio device to
pulse in Ledfx is the only way it will work.

Have you tried changing your device in ledfx to pulse?
https://ledfx.readthedocs.io/en/latest/directing_audio.html
Again no idea if this works, I don't know nor use
ledfx :) Just trying to help out.

Hi Mark,
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.

Can you use paplay instead?
That is the pulseaudio aplay drop-in
replacement.
I'm guessing you won't have "device or
resource busy" errors when using paplay.
I did not test this! But do let us know if
it works for you :)

I have a Raspberry Pi 3b with a
Hifiberry Amp4/DAC hat runs Moode Audio OS.
If I pick |Pulse| as they audio device
in LedFx and play a sound file with
|aplay sound_file.wav| my leds react to
the music.
The problem is that after |aplay| 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:
|MPD error Failed to open "ALSA
Default" (alsa); Failed to open ALSA
device "_audioout": Device or resource

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 |aplay|.
