Librespot + LibreELEC 9.1.002 -> Change Playback audio device

Hi,

before updating LibreELEC to 9.1.002, there was a configuration item inside librespot addon to configure the audio playback device (independently from default audio device of KODI):

Default Audio Out = HDMI (for video media playback on TV)

Librespot Audio Out = Analog Audio Device (for Spotify music to stereo system)

Not this configuration item has disappeared in Librespot

Currently the system starts the plugin with these paramters:

librespot --backend pulseaudio --cache /storage/.kodi/userdata/addon_data/service.librespot/cache --device-type TV --disable-audio-cache --name Kodi (HTPC) --notify-kodi --disable-discovery

If I try to change the backend to "alsa" to select hw:0,0 card (stereo audio), I get the message "invalid backend".

Do you have an Idea how to route audio to analog audio out?

Nobody?
