[SOLVED] Problem playing High Rez File

[Tim Curtis]

If there is no distortion when source is USB stick it would suggest the problem is external to the SIG, Power supply or moOde software.

One possibility is that noise is being injected via the Ethernet cable. The way to determine that is to use a WiFi adapter and see if the noise disappears.

Regarding software issues, one of the earlier posts showed the port speed of the Ethernet connection was 100Mb/s and not 1000Mb/s as I would have expected. http://moodeaudio.org/forum/showthread.p...3#pid15053 This could indicate some sort of compatibility issue between the Ethernet port on the SIG and your Switch, or some other network issue thats not showing up in the stats.

Here is output from eth0 on my SIG. Its connected to my ASUS Router's built-in Switch. Note Speed: 1000Mb/s

Code:

pi@rp3:~ $ ethtool eth0
Settings for eth0:

One other log to examine for clues is the kernel boot log

Code:

dmesg

Example from my SIG

pi@rp3:~ $ dmesg | grep eth
