Roon RAAT and "An audio file is loading slowly"

[daniel.avasilichioaei]

I made the test: same result/issues. I made a second test after I disabled all options containing "Offload", but it doesn't help: the issue is there.

Daniel, I wonder whether we can test the idea that there is a packet loss problem at 1 Gbps but not at 100 Mbps.  One way to do that might be to use the psping command to send a series of back-to-back ping packets from your Roon PC to the Devialet and check what the rate of packet loss is.  For example:

Code:

C:\PSTools>psping -n 100 -i 0 -l 1420 192.168.73.2

Ping statistics for 192.168.73.2:
 Sent = 100, Received = 100, Lost = 0 (0% loss),
 Minimum = 0.37ms, Maximum = 1.21ms, Average = 0.54ms

(Needless to say, replace the 192.168.73.2 with the IP address of your Devialet, which from your WireShark traces is 172.168.168.102.)

Repeating this at both 1 Gbps and 100 Mbps might give us some more information about what's going on.

Note that this test doesn't use TCP.  My thinking is that if the Ethernet connection is showing some packet loss at Gigabit speeds, AIR over UDP might cope with that better than RAAT over TCP.

It's not an ideal test because if it reports packet loss we don't know whether they were lost from Roon to Devialet or vice versa, but either would cause problems for a TCP connection.

To everyone else: I hope this is not taking us off-topic or getting boring.  I'm assuming that what @daniel.avasilichioaei posted is related to the problems with RAAT over Gigabit Ethernet.

@thumb5 - I cannot run PSPING on my PC (Windows 10 Pro x64): I'm getting "Access is denied".
