Strange behaviour on USB - chrisc - 11-Sep-2019
Have a LE120, Serial: 02591A1, purchased 12 November 2015
Have used a USB connection from a Macbook since new. Have tried Ethernet and Wifi but find USB works best
Mac is configured to use Devialet USB Audio and likewise, JRiver and Tidal are configured the same
For the past 2 months, about 2 or 3 times an hour, the sound would disappear for a second, or less
In the last week this became 2 seconds
Today, it will play for 2-3 minutes, then there is silence. I have to restart the computer and the amp to get it back. Have tried different USB cables and the other USB port
Instead, tried Ethernet via the Devialet AIR. The ethernet radio button is green and the volume level displays on the Mac screen, but there is no sound
I can get sound via wifi, but starts off ok, then it is distorted
Any pointers please?

Hi chrisc, is the issue there also for locally stored audio or Tidal only? Since the issue got gradually worse I’d try with a different computer if possible to pinpoint the issue more and go from there.

Two separate fixes, both simple
Restarted the fibre router after letting it power down for 10 mins
Removed a USB cable that had been recommended to me by a friend
All 100% now

I am wondering if the problem you were experiencing is anything to do with the following problem.
In some ways it sounds similar

You would have had to have had a MacBook with a T2 chip and to have been running Mojave 10.14 to 10.14.3
The problem was fixed in 10.14.4 (I think) and is certainly fixed in the current release, 10.14.6

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

Panic (?) over....
Got an updated driver from UGREEN, re-did the IP address and it works
