Strange behaviour on USB

[chrisc]

The main machine is a 2018 Macbook Air.  USB works 100%

Not so Ethernet.  Followed the instructions as below and can see on Devialet Air screen, when Ethernet is selected, the volume changing when the control is rotated and the IP address of the Devialet

Alas no sound

Prepared a brand new Windows 10 machine, configured the Ethernet with the same address.  Still no sound.  Windows default sound device is Devialet AIR and likewise JRiver Media centre's playback selection is also Devialet AIR

No idea what to do next


The instructions for configuring the Ethernet port manually:

DHCP - OFF
Fixed IP address ( this is an example ) 192.168.0.77
Network Mask - 255.255.255.0
Click OK.
Downloaded the settings to the SD card.
Put SD card into Devialet and restart.
Ensure Ethernet input is selected on the Devialet
On the PC choose Network
Select Ethernet
Choose Configure IPv4 - and set to "Manually"
IP Address - set to 192.168.0.78    ( note this is exactly the same as you set for the Devialet except the last number (.78)
Subnet Mask - set to 255.255.255.0  ( note this is exactly the same as you set for the Devialet )
Router - doesn't really matter - put 192.168.0.1
Under Status: it should be as follow:
Status: Connected
Ethernet is currently active and has the IP address 192.168.0.78
