Hello all. I've recently set up a new computer for video editing and am excited to learn more about cinelerra. I am having issues with audio/video sync and am hoping someone might have a lead to the solution. If this problem is too tricky. I'm happy to try a different distro (is there one recommended by CInelerra developers?) and reinstall.
Here is the problem. The playback cursor jumps ahead about 4 seconds when I hit play, and playback is out of sync with the audio. In the Compositor, if I drag a clip into the Program window and click on the timeline to set the playback cursor somewhere, for example at 10s, when I hit play, the playback cursor jumps ahead about 4 seconds so that the video in the Compositor starts playing from 14s. The audio seems to still start from 10s. The audio is out of sync for the remainder of the clip and continues into the first 4 seconds of the next clip as well. If I switch the audio driver from ALSA to OSS, the cursor no longer jumps ahead when I hit play. With OSS, however, I don't hear any sound at all. (I don't seem to have a /dev/dsp device and /dev/snd/pcmc0d0c and /dev/snd/pcmc0d0p didn't seem to work.) For what it's worth, I also tried the Nudge and Audio Offset settings but they do not seem to fix the issue.
