Due Diligence

• I have done my due diligence

What can we help you with?

Setup:

• RPI 5 on a bookworm
• librespot 0.5.0-dev
• raspotify 0.44.0

Problem:
Raspotify is running but list of supported ALSA devices is empty. What may cause this?

sudo systemctl status raspotify
● raspotify.service - Raspotify (Spotify Connect Client)
     Loaded: loaded (/lib/systemd/system/raspotify.service; enabled; preset: enabled)
     Active: active (running) since Thu 2024-09-19 21:44:09 BST; 8s ago

        ------------------------------------------------------

Then the Raspotify is not recognized by Spotify connect, and I assume this may be because there's no available device for librespot.

Not exactly sure what this could be, your ALSA setup looks fine.
Perhaps the ALSA device is claimed by some other software running simultaneously?
