AXIS C8110 Audio Bridge Compatibility

Some users may desire to mix analog and network audio from multiple devices using an AXIS C8110 Network Audio Bridge device. When applied to the official release of DW Spectrum IPVMS 5.0.0.36529 and earlier, this device may not function on its own.

To resolve this compatibility issue, the DW Spectrum developers have provided a JSON resource that can be implemented to the DW Spectrum Server.

This article will outline where to copy the JSON file in the DW Spectrum Server folder to implement this fix.

**NOTE: Making changes to the core files and configurations of the DW Spectrum Server files is not recommended unless necessary to resolve a specific issue. Please consult with your Digital Watchdog service representative or with DW Support for clarification if you are unsure if this fix applies to your needs or to an ongoing issue.
