Problems Getting Started with Multiroom System (Pi 4 + Pi Zero Ws)

Project help balenaSound

Hi there,

I’ve tried to do my research before asking here, but I’m hitting some snags attempting to get a multi-room setup going, and would appreciate any pointers to put me in the right direction!

Current Hardware:
1x Raspberry Pi 4 | USB DAC | 32GB Sandisk Ultra Class 10 U1 SDHC
2x Raspberry Pi Zero Ws | USB DAC | 32GB PNY Elite Class 10 U1 SDHC

I’m using the Pi 4 as the master, and I’ve disabled Spotify, Airplay, and Bluetooth on the client devices to reduce the load. I’ve also disabled UPNP globally, as I don’t need it.

I’m able to connect to the Pi 4 Master via all desired services - Spotify, Airplay, and Bluetooth. I’m unable to connect to the clients via any service. I’ve tried testing them individually in STANDALONE mode with no luck. As they don’t have any onboard headphone jack, I haven’t been able to test them without their USB DACs.

Right now, I have a couple of hunches:

  1. The SD cards; I know the officially recommended models are the Sandisk Extreme Pros, and I’m happy to replace with those if this seems like the issue. Right now, the card running on the functioning master (Sandisk Ultra) and the PNY cards on the non-functioning clients should theoretically be comparable Class 10 U1 cards. The PNYs are testing at 90MB/s read / 20MB/s write; without having an Extreme Pro to test against, I’m not sure how that compares to the ideal.

  2. The USB DACs. The one running on the master is a Dragonfly Red that looks like it’s defaulting to 24/44.1 (S24LE) and the two running on the clients are cheapo dongles running 16/44.1 S16LE.

  3. The WIFI network. I’ve enabled QOS on my router, made sure multicast routing is enabled, and disabled NetGear Smart Connect (which groups the 2.4 and 5GHZ bands under the same SSID) in an attempt to optimize it, but my service isn’t always the strongest.

  4. OS discrepancies. The application type is 32 bit to account for the Pi Zero Ws, but I was only able to get the Pi 4 to run on 64 bit OS when setting up that device.

Variables I’ve tried experimenting with:

  • SOUND_MODE and SOUND_MULTIROOM_MASTER to force the master/client modes
  • AUDIO_OUTPUT to force the USB DACs
  • SOUND_SPOTIFY_BITRATE and SOUND_INPUT_LATENCY to lighten the load.

An assortment of error messages I’ve noticed in the logs:

  • multiroom-client: [Warn] (Alsa) snd_pcm_avail_delay failed: I/O error, avail: 2646, delay: 2037, retrying.
  • multiroom-client: [Warn] (Alsa) snd_pcm_avail_delay failed: Broken pipe, avail: 660, delay: 1887, retrying.
  • multiroom-client: Failed to connect to host ‘192.168.1.15’, error: Connection refused
  • multiroom-client: [Warn] (Resampler) Soxr not available, resampling not supported
  • multiroom-client: [Error] (Controller) Failed to send hello request, error: Operation timed out
  • multiroom-server: [Notice] (Server) Server::start: Can’t open device ‘pulse’, error: Connection refused
  • Alsa error PCM open ALSA function ‘snd_pcm_open’ failed with error ‘ECONNREFUSED: Connection refused’

Thank you!

% Hi Sam, balenaSound developer here, let’s see if I can help you out! I’ll add a few comments to your previous post and then add a few suggestions.

I’m using the Pi 4 as the master, and I’ve disabled Spotify, Airplay, and Bluetooth on the client devices to reduce the load. I’ve also disabled UPNP globally, as I don’t need it.

The PNYs are testing at 90MB/s read / 20MB/s write; without having an Extreme Pro to test against, I’m not sure how that compares to the ideal.

Those SD cards should be perfectly fine for the job. If anything we recommend the Extreme Pros because they are super resilient and battle tested, but any SD card should work on paper.

  1. The USB DACs. The one running on the master is a Dragonfly Red that looks like it’s defaulting to 24/44.1 (S24LE) and the two running on the clients are cheapo dongles running 16/44.1 S16LE.

It doesn’t seem to be the case, but you could test all DACs on the Pi 4 just to be extra sure they are in working conditions. The audio service in balenaSound uses PulseAudio internally which should be able to resample the audio.

  1. The WIFI network. I’ve enabled QOS on my router, made sure multicast routing is enabled, and disabled NetGear Smart Connect (which groups the 2.4 and 5GHZ bands under the same SSID) in an attempt to optimize it, but my service isn’t always the strongest.

This might be worth exploring after we rule out a few other things (see my debugging suggestions above). For starters all Pi’s should be able to talk to each other reliably over the network. You can rule out a bad network by SSHing into each Pi, pinging the others and checking the results.

  1. OS discrepancies. The application type is 32 bit to account for the Pi Zero Ws, but I was only able to get the Pi 4 to run on 64 bit OS when setting up that device.

That’s fine too, they can coexist without problems :slight_smile:

I don’t think any of the points above here are the culprit, at least I would like to check some other basics first. In order to help troubleshooting I’ll need the following:

  • IP address of each device
  • logs for the audio service (for each device), try to capture the initial output when the service starts
  • output of the debug endpoint. Use any browser to hit http://<DEVICE_IP>:3000/support and share back the output, where <DEVICE_IP> is the IP address of each device

Also, I would suggest to remove any custom variables (SOUND_MODE, AUDIO_OUTPUT, etc) you added before running these just so we all agree on the starting point.

Let me know if you need more details on any of this points, happy to assist!

Hi tmigone,

Thanks so much for offering your help, and for your detailed response!

I tested all of the USB DACs on the Pi 4, and they were all able to output audio. Not sure if its relevant, but all of the DACs are USB A male, so while they can plug directly into the Pi 4, they need a Micro USB to USB A female OTG adapter to connect to the Zero Ws.

All variables on all levels have been removed, so we’re starting from scratch. Also, the Pi 4 is now using a Behringer UCA222 instead of the Dragonfly Red (it’s got an input I’m hoping to use to add a turntable to the setup once everything else is working).

IP addresses are:

Pi 4 Master - Living Room: 192.168.1.14
Pi Zero W - Kitchen: 192.168.1.13
Pi Zero W - Dining Room: 192.168.1.15

Logs for the audio service at startup and outputs of the debug endpoint are attached.

Audio Service Startup Log 192.168.1.13.log (2.0 KB) Audio Service Startup Log 192.168.1.14.log (1.8 KB) Audio Service Startup Log 192.168.1.15.log (2.1 KB) Debug Endpoint Output 192.168.1.13.log (8.3 KB) Debug Endpoint Output 192.168.1.14.log (8.4 KB) Debug Endpoint Output 192.168.1.15.log (8.2 KB)

I was also able to pull the following errors from running diagnostics on the devices:

192.168.1.14: check_service_restarts: failed! Some services are restarting unexpectedly: (service: /multiroom-server_3183447_1666757 restart count: 16)
192.168.1.13: check_timesync: failed! Time is not being synchronized via NTP
192.168.1.15: check_timesync: failed! Time is not being synchronized via NTP

Thank you again for your help. I’ve been very happily using a standalone Balenasound setup for months now, and this is my first foray into making things more complicated, so I really appreciate the assistance!

Looks like all the clocks are out. Try systemctl restart chronyd ; watch chronyc tracking until the problem is evident or the RTCs are synced…

18

Okay, I’ve run systemctl restart chronyd ; watch chronyc tracking a couple of times over the past couple of days.

It seems like every time I run the sequence, all the clocks are out at the beginning, but they quickly stabilize much closer. Here are outputs at the beginning and end of running the command every two seconds for a few minutes:

Hopefully that’s helpful - let me know if I can provide any more diagnostic info.

Hi, @samaero! thank you for providing that diagnostic feedback.

It seems like every time I run the sequence, all the clocks are out at the beginning, but they quickly stabilize much closer. Here are outputs at the beginning and end of running the command every two seconds for a few minutes:

This is normal for NTP. It’s actually pretty interesting how it works if you want to check it out: Network Time Protocol - Wikipedia .

But on to your problem…Is it safe to assume your tried balena sound after restarting the chronyd? If not, I would try again now that the clocks are synced.

21

Hi @zwhitchcox, thank you for chiming in! Good to hear that the NTP is synching correctly. Is that typically something that needs to be re-synched periodically, or every time the devices restart?

Yes - I’ve tried again and am pleased to report that I’ve got sound! The clients are playing, but stuttering pretty heavily and not quite in sync.

Things I’ve tried to attempt to stabilize the system are:

  • Adding & adjusting the latency settings. (I’m a little unclear on which of the three latency settings (SOUND_INPUT_LATENCY / SOUND_OUTPUT_LATENCY / SOUND_MULTIROOM_LATENCY) to tweak here.)

  • Disabling unneeded services on the clients (Spotify, Airplay, Bluetooth, UPNP). I’ve also seen a few posts regarding WIFI & Bluetooth interference on the Pi Zero Ws which can be resolved by disabling bluetooth. I’m not sure if disabling the bluetooth plugin is enough to accomplish this, or if I would need to disable it on a system level?

All of the devices are currently connected via WIFI, but I could also look into changing the setup so that the master is connected to the router via ethernet if needed.

22

@samaero - I’ve pinged @tmigone to take a look back at this thread, but in the meantime can you attach some logs here for us please? Of interest, we’d like to see the logs from the ‘audio’ service on both the master node, and the ‘audio’ service on one of the clients.

You can grab those logs easily from the balenaCloud dashboard, and filtering via the drop-down menu in the Logs terminal at the top-right when viewing a device’s details. Thanks!

24

Hi @dtischler, thank you for jumping in! Log for the audio service on the master device is below:

The clients aren’t showing any info under the log of the “audio” service, although the service is shown as running (and there’s music coming out of the device!).

25

I checked the logs again after restarting all of the devices, and the clients are now showing logs for the audio service; here’s one of their outputs:

I’ve tried a few more strategies to reduce stuttering on the clients by setting SOUND_INPUT_LATENCY to 2000 at the fleet level, and reducing the Spotify bitrate (SOUND_SPOTIFY_BITRATE: 90) and disabling bluetooth entirely (Define DT overlays - “disable-bt”) at the device level, but I’m still getting stuttering / de-syching audio on the clients.

27

Hi @samaero I don’t see anything quite wrong on your logs. To be clear, the stuttering is only affecting the clients correct? Is the master device playback fine?

29

Hey @tmigone,

Yes, the master is completely fine - it hasn’t stuttered once since it went online!

I tried forcing all Pis into standalone mode, and the Pi Zeros were then able to play pretty cleanly, with only very occasional stutters.

31

Hi

Can you do a quick test? Can you ping - for lets say a few minutes each - from the master to your other devices, and see what kind of losses you are seeing?

This should help us identify if it’s a network issue.

33

hey @anujdeshpande - pings between devices below. Thank you for taking a look! Please let me know if you need more/different logs.

Hi, on a relatively OK WiFi network you would usually see the responses being timed in a 2 to 5 ms range. With yours it is much higher and I even see a value of 230 ms, which is may possibly indicate that the local network is not strong enough.
Thanks,

Hi @majorz, thank you very much for the info. I’ll look into getting the WIFI more stable and report back. It may be time for a new router, a WIFI extender, or to run an ethernet cord to the master device. I’m committed to getting this working though!
