Maybe, I have to convert the audio to a different file format. I’ve just found this here concerning the scrubbing of .wav-files. If I can’t fix that problem, then I can forget this course here. This constant sound skipping is really nerving and there doesn’t seem to be a reason why a sound sometimes is played and sometimes not. I also noticed that the more I scrub, the more my fan is working. Doesn’t “Cache” mean that the computer gets a faster access to the audio information? I also seems to me that Blender doesn’t cache the full audio but just a small portion and needs to refresh the cache. I’m really clueless 😥.
