same problem here

windows 10 - 64 bit / i7 3930K /  16GB /  gtx580 / nvidia 361.43 / lynxtwo-B soundcard - lynx mixer 2.0 build 23a - firmware 16.0

bad synchronisation with firefox/bsplayer/mediaplayer/divxplayer/netflix/edge

synchronisation gets worse with time

audio is faster than video

watching movies is doable but less engaging

 

the weird thing is, there is not much information to find about this on google

the only solution i know of now is going back to windows 8 but i'd better solve this

please help!

Change audio format to 16 bit, 44.1 KHz, also try to force HPET , run cmd as admin and type "bcdedit /set useplatformclock true ", if you want to reverse, type "bcdedit /deletevalue useplatformclock".

If that doesn't work, try to update motherboard bios.

thank you darth-father but the HPET trick doesn't work,

just as yesterday, the audio even starts looping after several minutes and it makes the movie to restart from the beginning and then play in a faster speed

restarting the movie solves the problem until the end but synchronisation is still not good

 

i will retry installing motherboard drivers

Turn off integrated audio from bios if you didn't already, you could also remove your lynxtwo-B card just for test. If the sound is ok with the integrated card, try to install your lynxtwo-B into another pci slot, maybe it's an irq or memory conflict...

i took out the lynxtwo soundcard

audio synchronisation is good good from the motherboard audio output

 

i have to tell you that this great soundcard is great with music, no problems here, the problem only exists with video

 

so how do i solve this? i can't find any lynx studio related problems on google

 

a practical solution could be to make the onboard audio default for television use

and use the lynxtwo-B for audio from foobar2000 to the mainspeakers and headphones

I've never played with this type of sound card, It could be a bad driver or a bad config, try to change sample clock source from Mixer-Adapter and enable/disable Drop frame from LTC generator. You could also install an older driver and mixer version.

that ltc part of the mixer is for external clock input; though i did try some changes but it didn't seem to help

i also installed an older mixer version from 2014, restarted the computer, but no changes

this video synchronisation problem is new, it accures since i upgraded to windows 10

Check if you have latency issues, install LatencyMon.

Start playing a movie and then run the program.

 

This is mine (Win 10 x64) running MPC-HC 1080p movie.

As you can see, the highest is actually the sound card driver "cmudaxp.sys", but it is normal.

Hello there, about 5 minutes into a video across any platform, web based, video player, etc; the audio will become desync'd with the video.

I've tried installing my specific drivers and tried different browsers and video players, yet the problem STILL persists.

 

Any ideas? 

I've done all that darth_vader recommended... LatencyMon still reports horrible results. Video is seconds behind audio after minutes of playback. I built this desktop 5 years ago; would a failing CMOS battery (CR2032) result in a clock that is always slow, and the out of sync audio/video? Any other ideas?

CMOS battery is only to keep BIOS settings when the motherboard is powered OFF.

 

Is your Sound chip built in ? or HDMI from video card ?

 

You might try installing a better sound card.

 

If you use VLC media player, it has an adjustment for out-of-sync audio tracks.

This computer has worked fine for 5 years. And it's all streaming video services (Vudu, Amazon Video, Netflix, Google Play Movies). They used to all work fine. All sites. All browsers. I've tried various combinations of hardware acceleration on or off... 3D and 2D rendering settings in chrome://flags ... I think darth_vader's suggestions above actually resulted in greater offset of audio leading video.

I've decided to just do a major upgrade to this Frankenbox which is 5+ years old. New case, mobo, cpu, ram, power supply, and sound card should arrive tomorrow. Reusing my blu-ray burner (which I never use), hard drives, and GeForce GTX 960.

 

BTW—I finally got VLC set up to play blu-ray (I installed VLC 32-bit, but was trying to use aacs 64-bit. Oops; reinstalled VLC 64-bit and it's all good). Local media blu-ray plays just fine; completely in-sync. Realized that even live YouTube streams get out of sync. Network based streams seem to be the only media affected.

actually the CMOS battery is also the power source for the motherboards RTC. :)
