Hi, Tonight Vegas 13 crashed while rendering a small file. No big deal, just reboot and all will be OK I thought, happens all the time. I rebooted, everything looked and sounded OK during editing. I rendered and the now the rendered files are full of audio issues; snap crackle pop, drop-outs etc. What happened? It had been working great for just about everything until after tonight's crash. So far I've tried different encoders, no improvement; different source files, no improvement; totally uninstalling a reinstalling V13, no improvement; rendering multitrack music files with Sonar Platinum, sound great. Any ideas? I've looked at all the audio settings I can find and everything looks OK. FYI - I use windows 10 and an Apollo Twin sound-card. Uh oh, I just noticed my mp3's are playing faster now. I think my audio clock may be messed up but I changed the buffer size and it fixed the mp3 speed, but then I went back and rendered in Vegas and that seemed to speed the mp3s up again and gave me another garbled render. Never had any issues like this before, maybe I can reload the Apollo drivers which are extensive. I also have another sound card I can try somewhere.
