I also tried it in VirtualDub 1.9 and amarectv 310 and get the same results. Thanks for this, i did manage to install the Dazzle Audio Driver but when i go in to Virtualdub2 the Audio Capture USB WDM source is not there to select and the video source is black if i select the Line Source. To install the older driver you need to go to control panel/device manager/dazzle device/driver/update driver/browse my computer for drivers/let me pick /have disk and point to the folder where the older driver is located. I tried a new capture card to see if that worked and that had the same issue Windows would just install the same AUDIO driver. My Dazzle worked perfectly before i had to reset my PC i had an older Windows USBAUDIO driver installed which was dated 2020 as mentioned in my earlier posts in this thread. Windows will not let me install the Dazzle Audio driver and it just keeps saying the best driver is installed for this device. It starts in sync, but then goes off, im almost certain the issue is the Windows USBAUDIO.sys driver which Windows insists it installs.

There is no quality loss, using this method. Both Video and Audio were set to "Direct Stream Copy". Under "Audio skew correction", I set delay at "-500". In VDub, I went to "Audio->Interleaving". As a work-around, I would make a corrected copy. The audio was always a half-second behind. Is the audio always out-of-sync by the same amount? I ran into the same problem using the Dazzle, Windows 10, and VDub. The only difference I can see is that now the Microsoft audio driver for the dazzle is a later version dated 2021. Im Using the exact same settings as before when I had it working perfectly. I try to do a capture the audio is out of sync.
