Hi B. Shah and all,
Did you guys ultimately get this resolved? I’m having what looks like the same issue.
Pi Zero W with HifiBerry Zero DAC + getting no sound. Doesn’t seem to matter if I am using SOUND_DEVICE_NAME and BLUETOOTH_DEVICE_NAME. Otherwise followed the same guide, used “i2c_arm=on”,“spi=on”,“audio=off”, and have tried both hifiberry-dac and hifiberry-dacplus as values for BALENA_HOST_CONFIG_dtoverlay.
I reflashed the SD but still seem to be getting no luck… for a bit I could connect on bluetooth and AirPlay, now seems to drop when I do. The relevant parts of the log seem to be:
ALSA lib pulse.c:243:(pulse_connect) PulseAudio: Unable to connect: Connection terminated
ERROR librespot_playback::audio_backend::alsa] Alsa error PCM open ALSA function ‘snd_pcm_open’ failed with error ‘ECONNREFUSED: Connection refused’
Any insight you guys might have gotten would be greatly appreciated. Thank you!
