Audio randomly goes silent

HeavyMetal wrote on 11/28/2023, 12:56 PM

Not sure where to start with this one, but sometimes (often times) when I am in the editor working, suddenly I will have entire tracks just go completely silent on playback. Wave form is still there, but when playing, it processes no sound. The sound mixer doesn't display anything happening. The only way I get around it is restarting the program. This happens multiple times an edit session and isn't brought on by any specific action. Sometimes as simple as zooming in or out on a timeline, or minimizing the program and then coming back to it, or just any other combo of actions I am not able to track.

Anyone have this experience? I experienced this with Vegas 19 as well as Vegas 21 which I just purchased yesterday.

I have tried both the Direct sound and Microsoft sound mappers with no change

What format are the source audio files?
Are audio plug-ins being used? If so so whet.
Is rendering affected (glitches and silent spaces)?

No plug ins applied. It seems to do the same for wav or mp3. As far as rendering, I have not tried that yet. I should add that sometimes the track plays as sporadic static/glitches sometimes, as opposed to being silent.

I have had that happen with several projects in V20. Does it "click" when you first press play on those tracks/events that aren't working properly?

I could be mistaken (memory isn't as good when sleep-lacking), but I believe it happened after crossing over specific parts of an audio clip... cutting out that spot in the audio track/event would fix it.

Do you have Sound Forge Audio Studio installed by any chance?
There is an issue with a 'low latency' driver that SF Audio Studio installs that can cause noise in Vegas and other programs with audio. Static and screeching is an often described symptom. I do not recall dropouts as a symptom though.
(SF Audio Studio is included with many versions of Vegas)

I've been having this issue for years as well. If I remember correctly this happens in Acid and Movie Studio too. File type doesn't seem to matter but I'll start keeping better track of it.

For me it usually seems to happen to the really short clips when I'm adding sound f/x for cartoons. Again if I'm remembering correctly, I think some of those clips also failed to render on export. Most of the time it happens to short clips just a few seconds or less. I don't remember it ever happening when I'm recording music tracks that are usually 1-4 minutes long.

For me it usually corrects after I close and re-open Vegas.

I was just able to check this. When rendering, the audio track that is randomly silent renders as silent. Other tracks still play. So basically as it plays in the editor preview is the same way it renders.

Only solved by rebooting the program. Incredibly annoying

@adam-thacker Next time that happens try changing focus to something else, such as a browser, maybe play a YT video (I don't think you need to) then resume focus on Vegas, that may bring the sound back until it goes away again.

Sometimes as simple as zooming in or out on a timeline

@HeavyMetal I've seen that too, both with waveforms correctly indicating the lack of audio, but also audio muted without waveforms changing.

I'd say at this point it happens almost every time I use the program at least once. Even in the middle of playing on the timeline it will just go silent, and only can be fixed by re-launching the program.
