# "Cannot Find Audio Hardware" error message

### Scope

This document applies to 25-Seven Voltair units, both Analog and AES.

### The Error Message

First, we ask to make sure that the unit is running the latest software, V2.5. That can be found here:

- [Voltair Software Update v2.5](https://telosalliance.com/uploads/25-Seven/Voltair/1601-00538-010%7BVoltairUpdate.2.5%7D.257)

If the software is up-to-date, another thing to check in the field is that all internal cables are tightly seated.

To check the interior connections:

1. Unplug the Voltair
2. Remove the top cover
3. Ensure that all audio cables inside are seated properly, paying particular attention to the area circled:

4. Power the Voltair back up and see if the issue persists
