balenaSound blueooth audio on Raspberry Pi 3: Sound skipping, dropping

Product support
1

I have balenaSound running on a Raspberry Pi 3. When I stream audio to it over Bluetooth from any device (even with my phone right next to the raspberry pi) the audio very regularly skips a bit, and about once every minute or two will cut out for 1 second or so.

I used balena-cloud-audiopi-raspberrypi3-2.43.0+rev1-v10.2.2.img and pushed the latest 0.4.4 balenaSound project from a Linux Machine. The bluetooth-audio, spotify and airplay downloaded and installed OK.

Is this bluetooth audio issue a common problem with the rpi3 and can it be fixed? If not, does the rpi4 have these problems also, or should I consider an upgrade?

2

Since you don’t want to have Wifi active, you can try disabling the interface at a hardware level. The Pi 3 has issues with Wifi/Bluetooth interfering with each other, so this might help and I would love to hear back if it does. You would need to set an application config variable in the balenaCloud dashboard for RESIN_HOST_CONFIG_dtoverlay and you want to set it to disable-wifi.

4

Thanks. I’ve set the variable and will report back after I test it.

6

I’ve set the variable and rebooted, but it seems the device is still visible as Online in the dashboard?

I’ve confirmed that dtoverlay=disable-wifi line exists in the config.txt, but Wifi is still connecting? (BT audio problem still exists)

7

OK - It’s weird that the Wifi wasn’t disabled, so I am going to ask a collegue to confirm this is something we directly support in balenaOS

11

Could you try setting the value to pi3-disable-wifi as it may be that our kernel is older than the one the RPi foundation has documented. Please report back if that kills the wifi interface :+1:

13

Thanks. This setting seems to have disabled the Wifi.

I wonder does this setting also disable the Bluetooth HW?

I wasn’t seeing the Bluetooth device any more, so I connected an Ethernet cable to check.

I see the Bluetooth service is restarting on a loop, with this message:

“31.10.19 08:19:14 (+0100) bluetooth-audio /bin/bash: relocation error: /bin/bash: symbol clo3%, version GLIBC_2.4 not defined in file libc.so.6 with link time reference

Hi, I am going to run it now and get back to you shortly.

Hi, I do not experience any issues when adding pi3-disable-wifi overlay.

What I did is:

  1. cloned the balena-sound repository
  2. pushed it to a freshly created application with balena push
  3. added RESIN_HOST_CONFIG_dtoverlay as pi3-disable-wifi in the dashboard Fleet configuration page
  4. rebooted the device
  5. WiFi interface is not available and everything seems to be working correctly:
Setting output volume to 100%
Connection notify volume is 75%
Restarting bluetooth service
Bluetooth agent registered
Device is discoverable as "balenaSound f7ba"

Did you made some modifications on top of the balena-sound project when receiving those errors? The glibc relocation error does not look related to that change as it indicates something is not installed properly in the container.

Thanks,
Zahari

Hi,

Thanks. I started from scratch as you did, and now have Wifi disabled and bluetooth streaming.

The audio skips and gaps are still there unfortunately. I have ethernet plugged in, and I can see the following from the log:

The audio skips and gaps coincide exactly with the Missing RTP packet and SBC decoding errors.

Hey @outhud9 I’ve been trying to reproduce this on my side. Unfortunately I only have a rpi4 to test with. I have been streaming music to it via bluetooth for the last 30 minutes or so (from my macbook). I haven’t noticed any drop outs and havent got those logs. Lets try figure out what is different in your setup that causes this, some questions from my side:

  1. ) does Airplay and spotify connect functionality work as expected, or is there drop out there too? (trying to determine if its some how network related)
  2. ) Does stopping the airplay and spotify containers improve the audio quality? (trying to determine if its a resource problem)
  3. ) What kinda of SD card are you using with your RPI3? Our team all use Sandisk Extreme Pro SD cards because they are fast and don’t get corrupt. (trying to figure out if possibly related to IO performance)
22

@outhud9 Also another debugging step would be to get an external usb bluetooth dongle and test that, with the internal bluetooth disabled. However I know not everyone has these dongles :stuck_out_tongue: . From googling around most of the threads related to missing RTP packet end in “I just got an external usb dongle and it all works” …which is not a very satisfying answer :confused:

Hello
I used to play around with balena-sound. Did you enable any bluetooth speakers besides the RaspberryPi ? Other bluetooth speaker devices cause packet loss if they’re too closely placed around I think.

Hi,
I have more or less the same issue, very low volume and mostly dropping every paquet in Bluetooth mode. I have already tried every single solution provided without luck.
I also tried redeploying the app to the rasp 3b+ I am using. Right now I am with a ETH interface only and established the variable to discard wifi usage. SD card is powerfull enough and the device has always plenty of resources.
Thanks in advance if you can supportbalenasound_fragrant-morning-19.02.20_17_48_48_( 0100).log (107.7 KB) 71930c46f85eabf18f2d49fb651d0858_2020.02.19_13.39.51 0000.log (596.8 KB) balenasound_shy-cloud-19.02.20_14_34_24_( 0100).log (102.2 KB)

This is the last log I got, what I am currently experiencing is a really LOW volume for spotify and a very low volume + crippling for normal Bluetooth audio.

Hi @Alejandro,

Similarly to what Shaun asked @outhud9 , have you been able to replicate this with an external BT USB dongle? These issues do seem to point to the onboard BT setup, and it would be good to rule them

Another question is how far the Pi and streaming machine are away from each other. Obviously if they’re in the same location, you shouldn’t see any problems, but if there’s a significant distance between them (or there are a large number of other BT nodes in the same area) then this will also have a detrimental effect on playback.

Best regards,

Heds

Hi Hedss.
Thanks for the fast reply. Out of desperation I ordered a BT donlge yesterday because I really want to give my Pi this role as I think it is neat. Now let’s see if I can make it work, any advice or shold the system just recognize it right away?, the model I chose is TP-Link UB400.

About the distance…every probe I made was just dropping audio from either a laptop or a mobile phone from within 30 to 50 cm.

I have also commented here Unable to Use balenaSound on Raspberry Pi. I uploaded a photo about the product so I do here. I am confident that is not cables or other stuff outside the Pi.

This is really frustrating. I commited again the build and still no luck after trying every single BT related command out there.

I eventually managed to install the dongle, not much of an issue. What I was not able at all was to deactivate delete the hci0 which is the onboard Rpi3b BT controller, to have the hci1 giving service exclusively.

I tried the power on command for example but it does nothing really, though it says the controller is off

I would like someone to explain the way to set the system variable as someone stated something like “pi3-disable-bt” is possible. Any help?
And how do I up the volume to the max?
Thanks

Hi Alejandro,
disabling bluetooth using the overlay should work. I found a post ( https://www.raspberrypi.org/forums/viewtopic.php?f=28&t=146598 ) that claims that pi3-disable-bt-overlay shoud do the job.
To do it in balena you can follow this guide: https://www.balena.io/docs/reference/OS/advanced/#setting-device-tree-overlays-dtoverlay-and-parameters-dtparam

Hi samothx,

I regret to confirm that the variable I set following the url notes is not working. I have set the variable as you see, like I did in the beginning to disable the WiFi module

After rebooting I see it clearly and can connect to ir with the mobile phone.

Im very pleased for your help guys, but due to my low spare time I am moving to other project like volumio / Musicbox.
Thanks!

Sorry it didn’t work out Alejandro, hopefully one of those projects works well for you!
