Denon Systems - Custom Buffer

[Robert Welch]

TuneBlade Enthusiasts,

Issue Observed:  Some AirPlay receivers work while Denon receivers do not.

If you have Denon / Marantz receivers or speakers that support AirPlay (see link below), you may need to configure a Custom Buffer Value instead of using the default Real-time streaming buffer size.  Experienced is that some AirPlay receivers, such as the Apple Airport Express, will work just fine while the Denon devices indicate connected, but no audio is output.  The TuneBlade logs will not indicate any errors since the connection is established successfully and using the proper CODEC. 

Steps to adjust the buffer values: 

First, configure the custom buffer value in TuneBlade Setting (cog wheel at the top of the TuneBlade GUI).  The value may need to be increased to suit your environment. 

TuneBlade Preferences -> AirPlay Streaming 

Custom buffer size: 406 ms

Click the Apply button

In the TuneBlade GUI, enable the "Custom Streaming Mode" by clicking on the button at the bottom.

Note that this tool does not work well when other Bonjour tools are running such as TuneBlade.
