To mute: right-click on the audio clip, then select Switches:Mute.

To delete: click the Ignore Event Grouping button on the toolbar at the top of the screen, select the audio event, and delete. Click Ignore Event Grouping button again to keep re-group events.

Mikey, thanks for the reply but it's still not working! This is driving me crazy. I select a clip and associated video by double-clicking on one clip out of dozens in the timeline. I then right-click on the selected clip, go to Group to click Ungroup but ALL selections under Group are faded, as in not available. Any other suggestions?

When you remove the audio, I hope that there is other audio to fill its place, that's why recording "room tone" is an important part of production. If you don't, then the viewer will get the impression that the audio just failed.

An alternative is to insert a volume envelope on the track or audio bus and just dip it at the desired locations.

Okay so this method (delete: click the Ignore Event Grouping button on the toolbar at the top of the screen, select the audio event, and delete. Click Ignore Event Grouping button again to keep re-group events.) worked.

Just a reply to the person who suggested replacing the audio....

I am taking a portion of the video (20 seconds) and stretching it out to make a slow motion replay. Since the non-slow motion clip has music in the background, when I slow it down the music sounds like loud slow motion noise, which is why I simply want to delete it.

You didn't do it the way I suggested - click on the clip to select it (NOT double click). Hit the letter "u" to un-group the audio/video. Click on the audio portion to select it and hit the "delete" key. I just did it again to make sure I hadn't forgotten something (wouldn't have been the first time). Works fine with any clip I have on the timeline (Vegas 9.0e) but I have also used that method in Vegas Movie Studio with no problems in the past.

If you want to mute one EVENT. Hold the cursor near the top of the track and it will change to a HAND. Left Click and drag the line down, that will adjust the audio level for that event only. Bring it all the way down to mute. This way if you want the audio later, it is there in sync.

For deletion, it seems to me the simplest way is the "u" (for "ungroup") version mentioned above that I use all the time: click on default grouped vid-audio, hit "u" key, then click on the audio file only, delete it. Done.

I go with DaveT2. Why delete the audio if you just want to drag the volume to zero? Another way is to click on the track then hit 'V'. This'll give you a rubber band to drag the volume up/down anywhere in the track to your hearts content. Just double click on the band to create a control point where you want it. Or.....hold down shift and then 'draw' with your pointer on the track. Vegas has so many ways to do what you want!

There's also right-mouse-button click / Switches / Mute. That's my usual choice.

Good points on keeping audio instead of deleting. In my case, I know I don't need it, so I delete them for I replace with music and so having extra empty or muted audio tracks just clutters up the project. Each situation warrants different approach.

Don't be lazy in the future. Read the manual.
