I followed the instructions listed in the 2 links: [Turn your old speakers or Hi-Fi into Bluetooth, Airplay and Spotify receivers with a Raspberry Pi and this step-by-step guide](https://www.balena.io/blog/turn-your-old-speakers-or-hi-fi-into-bluetooth-receivers-using-only-a-raspberry-pi/#hardwarerequired) and: [Build your own multi-room audio system with Bluetooth, Airplay, and Spotify using Raspberry Pis](https://www.balena.io/blog/diy-raspberry-pi-multi-room-audio-system/) yet I can only hear audio output from one device. I have a raspberry pi 4 and raspberry pi 3B+.

Hi @sameer-gupta7447. Could you please make sure you are using a newer version of the balenaSound project? I see here [https://sound.balenalabs.io](https://sound.balenalabs.io) that our newest version is v3.4.2. You can use the “deploy with Balena” button to push your code. Moreover, you can [read here](https://sound.balenalabs.io/docs/support#troubleshooting) some workarounds about audio issues and how to resolve them. You can also find this useful piece of advice at the second link you’ve shared with me: `Note: You can mix device types as long as your application type supports it. A great way of maximizing device compatibility is to select Raspberry Pi 1/Zero as your application type. This enables you to add any board from the Pi family, and even the balenaFin. ` Hope these tips help. Please let me know if you have any other questions and I’ll be happy to assist further.

I used the deploy to Balena and it is deploying v3.5.2. It says that the build was uploaded successfully, but it has been about an hour and it is still running. I will update with what the outcome is. I also built a new application with Rpi zero as application type. ---

Hi Sameer, Could you get your device to update? Did you manage to solve the problem? Please let us know if we can help with anything else ---

I could not get the device to update. It still says it is deploying. It seems to be stuck. Although, when I click on the deploy, it doesn’t seem to be running any processes. ---

Hi there, might be the device has some problem unrelated to the application you are trying to deploy. There is a “Device diagnostics” section on your device dashboard page (check the sidebar on the left side) where you can run a few basic checks to test for some common problems. Can you run those and report back the result? ---

I have run the device diagnostics on both devices. What specific information should I look for in the output, or should I paste the entire outputs here? ---

Hello, It may be best if you post the whole output, so we can be sure we’ve covered everything.
