After running respeakerd with parameters /usr/local/bin/respeakerd --snowboy_res_path=/usr/local/etc/respeakerd/resources/common.res --snowboy_model_path=/usr/local/etc/respeakerd/resources/snowboy.umdl --snowboy_sensitivity=0.4 --source=alsa_input.platform-sound_0.seeed-8ch (as a systemctl service), and starting demo from Python folder, server will crash and report this:

Possible Solution

@Stayer Thanks for reporting. From the error messages, the crashing happens at the very beginning, when respeakerd's querying PulseAudio for the device "alsa_input.platform-sound_0.seeed-8ch". It might be caused by some configuration change of the PulseAudio on your system. What's the output of the following commands on your system?
