Hello, I recently posted here and made some progress with my system, but there are still problems. I deployed balena sound to my raspberry pi zero 2 (+ HIFI DAC Zero). The previous deploys didn’t work because the wrong version of docker was used. This was fixed, so now the sound supervisor installed without a problem. I tried to play music via spotify connect and BT but nothing worked. The terminal output continuously stated " Waiting for sound supervisor to start at 172.17.0.1:80". So i guess, that the sound supervisor caused spotify and BT to not work properly. When I try to connect to Spotify and play a song it disconnects immediately. The logs are as follows: spotify [2021-12-23T12:33:56Z INFO librespot\_playback::player] Loading \ with Spotify URI spotify:track:6qUEOWqOzu1rLPUPQ1ECpx spotify [2021-12-23T12:33:57Z INFO librespot\_playback::player] \ (310386 ms) loaded spotify ALSA lib pulse.c:243:(pulse\_connect) PulseAudio: Unable to connect: Connection terminated spotify spotify [2021-12-23T12:33:58Z ERROR librespot\_playback::player] Audio Sink Error Connection Refused: Device default May be Invalid, Busy, or Already in Use, ALSA function ‘snd\_pcm\_open’ failed with error ‘ECONNREFUSED: Connection refused’ Service exited ‘spotify sha256:b354887709a46e467701c9ea0ed1b59060e155973f9e65a25835d8b801c21de1’ audio Waiting for sound supervisor to start at 172.17.0.1:80 Restarting service ‘spotify sha256:b354887709a46e467701c9ea0ed1b59060e155973f9e65a25835d8b801c21de1’ spotify Starting Spotify plugin… spotify Device name: balenaSound Spotify 1738 spotify Volume normalization enabled. spotify Spotify audio cache disabled. spotify [2021-12-23T12:34:01Z INFO librespot] librespot 0.3.1 bbd575e (Built on 2021-11-26, Build ID: a6e0Ery3, Profile: release) spotify [2021-12-23T12:34:01Z INFO librespot\_core::session] Connecting to AP “[ap-gew1.spotify.com:4070](http://ap-gew1.spotify.com:4070)” spotify [2021-12-23T12:34:01Z INFO librespot\_core::session] Authenticated as “1155180833” ! spotify [2021-12-23T12:34:01Z INFO librespot\_playback::mixer::softmixer] Mixing with softvol and volume control: Linear spotify [2021-12-23T12:34:01Z INFO librespot\_playback::convert] Converting with ditherer: tpdf spotify [2021-12-23T12:34:01Z INFO librespot\_playback::audio\_backend::alsa] Using AlsaSink with format: S16 spotify [2021-12-23T12:34:01Z INFO librespot\_core::session] Country: “AT” When I try to pair my phone with the BT of the Pi it won’t work either. I alqready set the variable “AUDIO\_OUTPUT” to “DAC” and the custom config. “BALENA\_HOST\_CONFIG\_dtoverlay” to “hifiberry-dac” because I’m using the hfiberry zero dac. In case you need the .log file, I attatched it to this post. [log.txt](https://forums.balena.io/uploads/short-url/otDk3wsDRTpVA6bd42JPWgbs6oL.txt) (7.3 KB) Any ideas? Thanks in advance! ---

Hey Lukas, Apologies for the late reply. It seems you have several posts for the same issue. I checked the logs, but unfortunately, there are not clues as to why the sound-supervisor is not running. Can you please help with the following: - what version of balenaSound are you running? - what version of balenaOS are you using? - can you please enable support access or provide some more detailed logs? thanks ---

Hello! Unfortunately I don’t exactly know what fixed the issue, but I think I tried multiple deploys and releases. The problem is, that I’m not that experienced with the software to exactly explain which steps helped to fix this problem. Kind regards, Lukas ---

I think I’ve also tried different versions of sound supervisor, but my guess is that internal updates / bug fixes overall helped solving my issue.
