Have you done this yet?
If not, do it first and report back with the results.

Thanks for that Ken, I had gone direct to my stored folder of video files, should have opened Ulead.
The data reads:- microsoft AVI - open DML
25 frames data 3515 63 kbps
video compression DV encoder type 1 24 bits 720x576
audio DV audio PAL 48khz 16 bit stereo. I did search before posting but got 6700+ posts to my enq. missing sound in clip playback and trawled through many pages but no one had got it wrong as bad as me, but I always have problems with PC software, but I am learning !
thanks again for help silversurfer2

Yes Graham, I posted just below 'videoman on page 1 (in white and blue panel) I upgraded realtek sound driver to very latest, no better but updated to media player 11 and my test sound clip played Ok
But a new capture into ulead still had missing sound, until I messed with sound 'duplicate', but I think this is a bodge and may mess up elswhere, hope this and Kens earlier guidance means something to you experts !

The experts on Medion forum got me to download codecinstaller in case I have a bad/out of date codec (but I don't know how to use it) and microsoft detect dot net. this last one went through my files/prrogrammes like a food blender on steriods so perhaps it got things going, certainly in media player 11 !!! silversurfer2

Sorry SS2, I missed that one.

I am unclear though whether you just imported files into Mvie maker or captured them, or both. Did you capture as dv.avi in movie maker? Or use the preset which is wmv and not a good test of if it's working proerply when compared to VS.

If you can capture ok in Movie Maker then it must be VS that is causing the problem.

If you can duplicate the sound from one channel and get it to play ok in VS then it could be due to the way you recorded the sound on the cam, or the settings chosen in VS.

Play the video on the dv casstte in the cam and turn on the properties of the system so that it tells you what audio is being played back, does it say 12 bit or 16 bit?

I think you may have something with that skier. I have some old video that I recorded on an old Sony BetaCam. It of course recorded only 12 bit audio, not 16 bit. Loading these into VS, the audio only plays on the Left side. If I duplicate the Right audio, then I get no audio. I wonder if this is what Silversurfer2 is experiencing?

Hi guys, suddenly got busy!! first can't be sure how it was saved into movie maker, think I just dragged file into captue area, not a fresh from my camcorder. I was using a known clip that was not playing in Ulead. I can do another 'from scratch' test tomorrow. Same with media player, the files that would not play in 10 seemed ok in 11.... but this was after i did the dot net thing!
I have just done the camcorder test,
UVS AVI type 1 pal panasonic MSDV DV audio no mention of 12 or 16
but then battery on cam went down and system defaulted to
PCM 16 bits 713XBDA analog capture 320x240 YUY 2
hope this means something SS2
Sorry forgot Vidoman comment, I think the sound is already saved on capture (as it plays ok in 'Project' but the duplicate bodge somhow copies one (left/right)part of the sound and I imagine allows editing/doubing to be done on another track...I think ! SS2

Like I stated previously, if your source video clip's audio is recorded in 12 bit, it may only be playing on one channel, either the left or right. So if you double the wrong channel, you get no sound. Doubling the correct one, allows the audio to be centered, appearing as a stereo sound.

A true test needs to be capturing a fresh piece of your camcorder tape using movie maker.
Here's how to do it in movie maker,

Ok graham, I'll give it try tommorow, thanks for the lead to the movie maker guild. My camcorder is fairly new and tape recorded in std. play which I think is 16 bit, pehaps long play is 12 but I never use it SS2

No, most video cameras for some unknown reason with the audio set to 12 bit by default, and you normally have to go into its memory to change it to 16 bit. There will be a reference to it in your camera manual.

Hi Ken, thanks for advice. I have checked on my camcorder, in the playback menu. You are right, it says the following:-
12 bit audio ^(arrow head) points to ST1 (the other options are) ST2; MIX.
I must dig out the manual ('missplaced at moment!'), it may be poss. to select MIX to keep all sound ?
However....forgive me if wrong (I come to computer editing from S VHS background, tape/jog shuttle/sound mixer, so PC procedures, edit progs are black magic to me!) .
But, if my footage, originally recorded it would seem in 12 bit will play normally on my PC in 'project' and (clip/project) WHEN the AVI's are copied across from my H/D to my brothers laptop (using Ulead 11) would this not negate the idea that there is an element/track in the sound missing in the files held on my PC ? It may be that I am 'prodding the wrong donkey here'. As no one else seems to have this problem it's likley not a Ulead fault ?
This is why I am checking out Medion forum as well. They feel I have an out of date Ulead audio codec or a realtek electronic 'jumper' miss set. There seem to be so many variables ??? my brother says "full reinstall, you have probably addleld the registry" whatever that is !
I'd be happier with my old S VHS tape to tape !
Seriously I will try the 'experiments' suggested and post back ASAP

Hi guys, I'v been experimenting all afternoon (and tearing my sparse hair out!) I have been through the guide note from jonesgroup to check my preferences are correct.
I have made new capture into win movie maker and Ulead. I could'nt find how to change my panasonic to 16 bits so I did it in 12 and borrowed a friends Sony TVR 355 digital 8. it has 12 bit as default and option on 16, I did both. all three capture 'tests' play sound in movie maker. but, none with sound in media player 11(however one little piece I experimented with a few days ago will play sound in media p. it's file is wmv, audio/video file, forgot how this came about) !!!
Bad news in Ulead.
Only hear sound in 'clip' if I do the duplicate bodge.
Doing this with 'sound speaker' (next to timeline view) clicked I open 'suround'. I could then see that in clip I had no bars moving in the stereo gauge (but I hear sound) and in 'project' I hear sound but had only left bars moving ???

some data from my capture files:- microsoft AVI ; 24bits; 720x576; 4.3 ; 25fps; lower first; DV encoder ; type 1; ulead studio;
EDIT. audio channel stereo; AVI type 1; DV audio; PAL; 48 khz 16 bit ; custom, I truely hope this all means something, I'm running out of ideas... and no feedback from Medion forum, think they have given up ! SS2

VS11 certainly doesn't install any 'out of date' audio codecs. In fact, I am not certain that it installs anything much by way of audio codecs apart from Dolby and mpeg layer 2 (the latter as part of the mpeg MainConcept codec(s) it uses by default). All the rest are installed either as part of Windows or other programs.

I don't think the 12 bit/16 bit business is the cause of your problems -- though it would be good if you could find your camera Manual and sort out was ST1 and ST2 means. Like most of us, the camera will happily record using 12 bit audio. It's main purpose apparently is leave some bandwidth for attaching external microphones or something like that. It's just that most of us just use the camera microphone, and 16 bit gives better quality... In any case, if your existing video was already filmed using 12 bit, nothing can change that now. The resetting to 16 bit will only affect new filming.

As for experimenting with a Digital 8, I trust you played back a digital 8 tape, rather than put in an old analogue tape. There is a bug in VS11 which will not allow proper capture from Digital 8s using analogue tapes filmed on analogue cameras. (I know from first hand experience -- and it was not fixed in the VS11 patch or Power Pack, though other aspects of DV/analogue capture were fixed...)

But I am out of ideas as to what the real source of your problem might be.

Hi Ken, first i am still using Ulead 10 as I tied to upgrade to 11 (hoping to overcome this sound prob)but found it was hanging/blocking access from my panasonic so to try to progress my editing I went back to 10.
Of course I did use digital recorded tape, although I have boxes of old 8mm anologe to eventually do (and i will bear in mind your comments on bug in 11). As i am using the same firewire cable pehaps one channel is faulty. but even then the missing sound appears fine in 'clip' on my brothers laptop ???
looks like we are beaten. I may try an earlier tip to try a short piece right through to burning a DVD and see if the sound is scrambled. I wonder if a reinstall of my windows XP, (it has sp2 )will help ? Oh, best of luck with your new PM ! SS2

12 bit only records on one track, leaving the second track for in camcorder sound addition, like adding voice over or music.

The wmv file is made up differently to a dv.avi, which is why it probably works.

For now I would.

Forget you have a problem.

Duplicate the sound from the one channel to the other.

Edit everything that you have captured that needs doing now.

Don't capture anything else.

When done, come back and we can try sorting it out again, I hate doing large changes to my system in the middle of an edit, in case I loose everything.

I don't use VS, but perhaps someone can tell you whether there is an option to set the audio to 12/16 bit for capture?
