DSi 2.0 - Issues addressed in firmware v1.1.13.1

Problem Description

This release addresses a bootup issue that is encountered under the following circumstances.  All of the below statements have to be true to replicate the issue.

1. DSi 2.0 Amplifiers are connected via Analog Inputs to Dolby CP750 or CP950 Analog outputs.

2. The CP950/CP750 has a valid AES Input connection from a media Server.

3. There is no Audio signal present on the AES Connection.

4. Analog output gain on CP950/CP750 is high +6 to +16
 

It was found that the Dolby devices generate a 260kHz signal when there is no AES audio signal, but a valid AES clock is present.  This interrupted the boot sequence of the amplifiers. 

Problem Fix 

DSi2.0 firmware v1.1.13.1 bypasses a boot up sequence that was responsible for the interrupt.
This firmware was publicly fully released with Audio Architect 2.55.0.26. with the DSi2 firmware file date-stamped 12/16/2022. Its build date is 6/23/2022.

Additional Updates and Fixes Since Release v1.1.12.10

DSI2.0 v1.1.12.13 Support for DSi2.0 amps to be used in Audio Architect as either a proxy or static route was added.

DSi2.0 v1.1.12.11 Resolved a bug where the front panel would not show the Speaker Tunings applied and where output PO's were not being locked for Ch. 2,3,4
