This post from Chaz solved my audo rendering issues.

but I had to do the compatibility trick for Win7 (what I use) for it to complete the healing!

but while doing research I notice that Windows 10 — if that’s what you’re using — has lots of audio problems.

Update FYI: I solved my problem by uninstalling Vegas 15 and then restarting old versions of Vegas while holding down Ctrl+Shift and replying ‘Yes’ when it asks to “reset the preferences?” Got that from John Rofrano on another thread. So that solved the strange audio bug. Unfortunately you have to go through the work of re-doing all your prefs, which to me are many. But it was worth it. Was pulling my hair out. Oddly, Vegas did remember my old keyboard custom shortcuts, which was nice. So grateful.

I tried to re-install Vegas 15 with the same Ctrl-Shift trick, but it didn’t solve another rendering issues I was having with Vegas 15. Will try to first read up on what it means to start with Ctrl-Shift and then also select the dialog box “delete all cached application” which is displayed. Don’t know if I want to do that yet and possibly wipe out earlier versions of Vegas because they can’t be re-installed.

Hey Keith — I’ve encountered something similar; possibly related. I’ve been using Vegas Pro for years, but now after installing Vegas Pro 15, my old Vegas Pro versions have issues when rendering audio. Not sure if it’s a bug or a setting I accidentally hit.

For instance, if I have an audio track that uses a bus w/ a Sony VST, and the audio Master also has a Sony VST; then both effects will play on monitor, but the render will never be included from the VST on the Master. Verified this several times with different files (new or old). Further, if you take off the audio bus, then you get the Master VST on the render! Weird.

[E.g., if I have a vocal track that goes to a bus with Sony Chorus VST; and the Master audio had a VST with Sony Graphic EQ and all bass has been eliminated; then when monitoring you can hear the chorus effect and only treble; but when rendering you only get the chorus — unless you don’t use the audio bus — and then the EQ effect works. Bizzarre.]

I think this issue started when i installed Vegas 15. But the problem is that I use audio busses everywhere; so my Vegas experience is currently broken.

I’m on Win7 and have I’ve tried un-installing and re-installing MS Net, various versions. I’ve also tried playing with the audio devices as well. No success.

I hope this is a simple error on my part; and that you can find an easy answer; but my guess is there is some odd things going on with Vegas 15 audio rendering.

Best,
Dave
