AIR and Win10

[Manfred]

Hi,

I have a PC (Office) and HTPC (Living Room) with JRiver MC 21. I upgrated both to Win 10 last week.  ÁIR has never worked for me (White Noise, cracking ...). I am using USB up to now.
My Network is:

• PC-> FritzBox Cable 3660 (WLAN off)-> AVM 1750 E (LAN Bridge)-> AVM 1750 E (WLAN Bridge) ->D-200 (Wifi)
  

• FritzBox Cable 3660 (WLAN off)-> AVM 1750 E (LAN Bridge)-> AVM 1750 E (WLAN Bridge)->D-Link Switch ->HTPC (Killer LAN, Intel LAN Fix IP. Adr. for D-200) ->D-200 (Ethernet, Audioquest Cinnamon)
  
• NAS->D-Link Switch
  
• HTPC (Killer LAN)->D-Link Switch->AVM 1750 E (WLAN Bridge) ->D-200 (Wifi)
  

I have all type of FLAC files up 24 bit/192 kHz. Playing though the PC (Files are stored on SSD for testing) I have played music for hours using Wifi without any problems. Using the HTPC I have played music now for around 50 hours without white noise using Ethernet or Wifi connection. I had 3 times cracking if using Ethernet, but the reason for that could be related to using Memory Play with JRiver. JRiver loads the Files with around 800 Mbit/sec from my NAS going through the same switch, when JRiver already started playing the file and both workloads are using the same switch. Playing through WIFI - no problems up to now. Could play Supertramps Crime of the Century in 24/192  without problems. The sound through Wifi using Air is much better then through USB (SOtM tX-USBexp Audiophile PCIe to USB Audio Card + Transparent Audio Performance cable 1.5m)

One week further now without white noise either through Wifi or dedicated Ethernet. I further optimized Win 10. The antivirus under Win 10 is an aggressive process. I excluded several folders and processes: 
..\Devialet
..\Devialet USB
..\J River
..\Logitech
..\DevialetAir.exe
..\JRWeb.exe
..\JRWorker.exe
..\Media Center 20.exe
..\SetPoint.exe
Using AIR through the dedicated Ethernet port for streaming no issues so far. Wifi depends on the signal strength, must be > -49 db else I get stuttering. Also if using Wifi there should be no concurrent workload on the network devices. If I copy a file with 100-200 Mbit/sec through my AVM repeater and also want to use the same repeater for High Res streaming stuttering begins immediately. CPU of the repeater is not designed for this kind of workload.
I have Air 2.1.4ß. My CPU is i7-4770T running at 3.5 GHz when playing music and creating a CPU workload of 2-3%. When playing Supertramp "Rudy" in 24/192, Air creates a network stream of 8.8 Mbit/sec through the dedicated Ethernet port.
