I have always used bitstreaming: on, which is essential for decoding Atmos, DTS-X, etc. signals in the pre. It works perfectly for me too with direct audio, but being the device used by Windows (also for system audio) it seems to have a negative impact. Instead with Wasapi, the device is for exclusive use by JRiver MC. However, I solved: the problem was that I had set the minimum buffer in the Wasapi audio device settings, so as not to have a delay with respect to the video. I reset 100ms and the defect disappeared. The problem remains that in some videos the audio is not synchronized and I have to do it myself...
Is there a way to have the audio automatically synchronized with the video, with the buffer set to 100ms?
Thanks.
