In the balenaCloud dashboard:

- Click on the specific device within your fleet and select `Configuration` in the left-side menu.
- Add an additional custom configuration variable called `BALENA_HOST_CONFIG_dtoverlay`. The value of this will depend on your DAC board (see tables below in each DAC category subsection).
- Add an additional custom configuration variable called `BALENA_HOST_CONFIG_dtoverlay`, and where necessary `BALENA_HOST_CONFIG_gpio`. The value of this will depend on your DAC board (see tables below in each DAC category subsection).
- Cycle the power by unplugging your device.

If you're using multiple devices with multiple DACs for multi-room audio, you'll want to do this process per unique device that is using a DAC. Do not set this variable fleet-wide as it will affect every device within your fleet.

### Supported DACs

These are the DACs that are known to work with balenaSound. If you have trouble setting one up, please reach us at our [forums](https://forums.balena.io/) where we'll gladly help you troubleshoot the issue. Please **do not** create new GitHub issues for supported DACs unless you've been instructed to do so by our forums support agents.
