Title: Video Audio out of sync (Lip Sync) using ethernet instead of USB
Post by: Manfred on October 06, 2014, 04:16:06 pm
Hello,

up to now I was using USB as connection method of choice to connect my HTPC (Local 3 TB WD Red disk inside the HTPC + SSD for OS etc.) to my Devialet using Devialet ASIO Driver. Video Clock on, Display Setting automatic change mode: on; running MadVR with smooth motion enabled.
Everything works great  :) ;D.

I am using JRiver 20.0.21. (Just updated before testing  :))

I am thinking to place my HTPC in a different room, so I tried the Ethernet connection with WASAPI (Devialet AIR) as audio driver.

Lipsync is not any more existent. Video and Audio is out of sync. I had Windows 8.1 firewall enabled, but disabling did not help.

HTPC is connected through a 5-port D-Link switch to the Devialet. Also there is an ethernet connetion from the switch through a PowerLan connetction pointing to my AVM Fritz!Box.

Any Idea why LipSync is not anymore working using Ethernet connection instead of USB?

Thank you very much for your help!

Best regards!

Manfred

Looks like it's adding a delay.
 
Media Center has options to deal with this: Tools → Options → Video → Advanced → A/V sync correction milliseconds
 
You probably need a negative value to get this back in sync.

Hi,

thank you very much for your help!

Using "A/V sync correction milliseconds" I got it back working , but its very sensitive (switching Windows Firewall on/off requires an additional correction.

So I decided going back to use USB connection. I only will move the local storage into a different room to increase the current 3 TB (only 20 GB left) using a NAS.
