Solved: Problem playing High Rez File
#31
I have run almost every following tests without any success

          - removal of my Switch (Prosafe Box) et direct connexion from SIG and DLNA server to my router (Freebox)
          - change DLNA settings in Jriver (Original Mode, specified output format, ..etc)
          - swap the PSU
          - running Wifi only
 
reminder :
      - I have the same audio problem with Volumio
      - I have no audio problem with previous USBridge


The very last track before sending back the unit to my reseller, could be related to the Asix driver.

Founded in  Infos.txt file in DietPi folder from Allo !!

Looks to me like different driver versions are downloaded for the 32-bit kernel and the 64-bit kernel.

From one of my moOde 6.4.0 players running the 32-bit kernel

Code:
pi@moode:~ $ uname -r
4.19.83-v7+
pi@moode:~ $ modinfo ax88179_178a
filename:       /lib/modules/4.19.83-v7+/kernel/drivers/net/usb/ax88179_178a.ko
version:        v0.1.4
license:        GPL
description:    ASIX AX88179_178A based USB 2.0/3.0 Gigabit Ethernet Devices
author:         ASIX SW
srcversion:     0DA7C4E6A1D359AEEF7588C


while from one of my moOde 6.4.0 players running the 64-bit kernel

Code:
pi@moode4b:~ $ uname -r
4.19.83-v8+
pi@moode4b:~ $ modinfo ax88179_178a
filename:       /lib/modules/4.19.83-v8+/kernel/drivers/net/usb/ax88179_178a.ko
license:        GPL
description:    ASIX AX88179/178A based USB 3.0/2.0 Gigabit Ethernet Devices
srcversion:     939AC35FBA15593ACF0DEC3


Further, the Allo install.sh script will download their "updated" driver for kernel 4.19.83-v7+ but not for kernel 4.19.83-v8+.

I ran strings on their "updated" driver and found these descriptors:

Code:
version=v0.1.4
license=GPL
description=ASIX AX88179_178A based USB 2.0/3.0 Gigabit Ethernet Devices
author=ASIX SW
parm=bGETH:Green ethernet configuration
parmtype=bGETH:int
parm=bEEE:EEE advertisement configuration
parmtype=bEEE:int
srcversion=0DA7C4E6A1D359AEEF7588C


which agree with the modinfo output for moOde's 32-bit driver (above).

Does your problem (which I guess is still "scratchy" playback?) still occur when you run with the 32-bit kernel?

Kent

Correct, the enhanced ASIX driver from Allo is only compiled for 32-bit kernel v7+. The other kernels contain the stock ASIX driver which still should be more than sufficient.

I'll need to have a look at System Config and prolly not list the 64-bit kernel if the SIG, otherwise it will just cause confusion.

My audio problem iwas very probably due to a fault during memory flash by Etcher who needed to be upgraded.

I started all over from the beginning by flashing moode 6.4.0 version from my Windows PC with Balena Etcher (as usual)

As Etcher was proposing an Upgrade , this time I choose to upgrade it (untill now every flash has beeen made with my
previous installed version wiithout any noticable problem)


I did check the Asix driver which was similar to the Allo Update one


pi@moode:~ $ uname -a
Linux moode 4.19.83-v7+ #1277 SMP Mon Nov 11 16:30:44 GMT 2019 armv7l GNU/Linux
pi@moode:~ $ modinfo ax88179_178a | grep version
version:        v0.1.4
srcversion:     0DA7C4E6A1D359AEEF7588C
vermagic:       4.19.83-v7 SMP mod_unload modversions ARMv7 p2v8
pi@moode:~ $

An now the audio is absolutly perfect ...

Thanks again to every one for your help
