Yes, you can connect the Google Home Mini to a soundbar to play music and other audio files via the soundbar, while simultaneously executing commands and actions via the Home Mini's Google Assistant.

Here are the steps you can follow:

## Connect to the soundbar
- Open the Google Home app on your mobile device.
- Select the device you want to connect (in this case the Home Mini)
- Go to the device's settings and select "Playback device" or "Default speaker"
- Select your soundbar from the list of available devices to set it as the default speaker.

## Play music via the soundbar
- Once the soundbar is connected to the Home Mini, you can play music and other audio files via the soundbar by giving commands such as "Hey Google, play [music track]".

## Commands and actions via the Google Assistant
- You can still perform commands and actions via the Home Mini's Google Assistant without affecting the music playback via the soundbar. For example, you can say "Hey Google, dim the lights" while the music continues to play.

This configuration allows you to take advantage of both devices: Listen to music via the soundbar and at the same time execute commands and actions via the Home Mini's Google Assistant.
