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 busy 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. $ aplay -l **** List of PLAYBACK Hardware Devices **** card 0: sndrpihifiberry [snd_rpi_hifiberry_dacplus], device 0: HiFiBerry DAC+ HiFi pcm512x-hifi-0 [HiFiBerry DAC+ HiFi pcm512x-hifi-0] Subdevices: 0/1 Subdevice #0: subdevice #0 $ amixer Simple mixer control 'Master',0 Capabilities: pvolume pswitch pswitch-joined Playback channels: Front Left - Front Right Limits: Playback 0 - 65536 Mono: Front Left: Playback 65536 [100%] [on] Front Right: Playback 65536 [100%] [on] Simple mixer control 'Capture',0 Capabilities: cvolume cswitch cswitch-joined Capture channels: Front Left - Front Right Limits: Capture 0 - 65536 Front Left: Capture 65536 [100%] [on] Front Right: Capture 65536 [100%] [on]
