Lost Audio
I have a Sony dsc-w290 camera.
I have videos with audio that I recorded with this camera.
I downloaded Sony Vegas Platinum and my w290 movies worked ok with audio.
I purchased Sony Vegas Platinum, installed it.
After experimenting with Vegas, it no longer recognizes a movie’s audio and I get this message:Audio Stream attributes could not be determined
Moreover, I get no audio on my renderings.
Quicktime plays the movies with video and audio but Vegas does not recognize the audio! -

What changed on your PC? What other software did you install since it was working? Things usually stop working for a reason. If it worked before, you need to figure out what changed. Have you tried rebooting?

Yes I tried rebooting.
I ctrl-shift double click the desktop icon to restore all default setting to Vegas 9.
I also removed Vegas 9 Platinum and reinstalled it from the CD including downloading the 9b update.
The result were the same…BAD!
The fact that Quicktime plays my .mp4’s with video and audio and Vegas 9 goes belly-up leads me the conclusion that it is problem local to Vegas 9.
Is it possible that something has got set in the Vegas 9 registery entries and it remains even though I removed and reloaded Vegas 9?
Very frustrating. -
Between the time you had the trial and then bought & installed it, did you update iTunes?
If so, then I can almost guarantee that’s your problem.
One cure is to uninstall the newest version of QuickTime but that will mess up iTunes.
MPEG-4 audio is no longer functional is the link to a Sony Knowledgebase article that may be of some help. -
iTunes is not a thing that I knowingly have on my pc but I have Quicktime.
Here is the time line as I recall it:
Bought Sony W290.
Its software played the movies ok.
I downloaded Free Trial Vegas 9 Platinum and it would not play my .mp4’s.
I called sony camera customer support which was no help.
After much googling on mp4 vegas, etc I found that Vegas 9 uses Quicktime.
So I pulled up Quicktime and updated it.
Then my downloaded free Vegas 9 worked ok.
What happened next is more than fuzzy in my memory.
I installed and updated my purchased Vegas 9.
Played with it, editing, rendering to AVI’s and WMV, etc.
Then I noticed I had lost audio but Quicktime played video and audio.
But I will try removing Quicktime and then download it from Apple.
Earlier this moring I order Quicktime Pro 7 to make things even more confusing! -
I had the same problem – I uninstalled Itunes (which seems to update Quick time) and then uninstalled Quick Time 7.6.5 – I found a link to Quick Time version 7.6.2 and installed it.
Audio now is recognized in Sony Vegas. -
April 2, 2010 After installing Apple’s latest Quick Time 7.6.6 Sony Vegas 8 now properly handles .mp4’s from my Sony W290 camera.
