If you can hear audio when you play the timeline, but you cannot see the audio clips on the timeline, it may be that the clips are on audio tracks that don't fit into the audio tracks window. Scroll or resize the window so that you can see higher numbered tracks.
Here's the scoop in 4 easy steps. Stop when the problem is resolved.
1. Open the Windows Audio control panel and make sure that the default recording device and default playback device are correctly selected (Start > Control Panel > Sounds and Audio Devices). 2. Launch Premiere Pro and select Edit > Preferences > Audio Hardware. Select Premiere Pro Windows Sound and click the ASIO Settings button. Make sure there is a X in the boxes next to the correct input and output devices. When in doubt, select them all. 3. If you're still having problems, update your sound card drivers. A web search may be necessary for this. 4. Get a new sound card.
I found a solution for my problem, at least in Vista. In the Preferences > Audio Hardware, I changed the Default Device to Creative ASIO (I have a Creative Soundblaster X-Fi gamer card). Then under the ASIO Settings, I changed the buffer from 50ms to 5ms. Setting the buffer under 5ms introduces a lot of crackling static noise in playback.
this is more a wild poke at the problem, but worth a shot anyway. Try going into your preferences, and find the Media Cache section. There's an option in there to clear the Media Cache - try giving that a shot. Moreover, to be really thorough, you might want to jot down the location, close Premiere & go & manually do the delete just to be certain. That'll force CS3 to re-index the MPEG files, and there have been some changes in that code since 2.0. I'm theorizing that there might be some niggling compatibility problem with pre-existing MPEG files that might be causing issues, but that's just a WAG on my part.
1) Capture using Type1 -- this will always be in sync. Unfortunately Premiere doesn't edit with Type1 files, so you have to change edit software; 2) Capture using Scenalyzer Live. ScLive offers an option that periodically checks the sync, and reestablishes the audio/video link -- unfortunately you have to pay for ScLive; 3) Install Premiere drivers that 'fix' the audio sample/Canon issue -- I thought there was such a thing for XL1 users, but I'm not a Canon guy and haven't followed up on this; 4) Capture in smaller chunks -- the cheapest solution, and one that offers other handling advantages. Build a batch capture list once that will capture an entire tape in segments size limited to 2GB. The clips are short enough to mask any sync error, the same batch list can be used for any tape, you gain the advantage of smaller file handling ... you can use the automate to timeline function to quickly rebuild an entire tape on the timeline with a minimum of effort.
a reliable (and free) way to solve MPEG-related synch issues in many cases is to add the utility VirtualDub-MPEG2 to your arsenal.
Use VirtualDub-MPEG2 (VDM2) to transcode your MPEG source files to DV.AVI files. But do it as a 3-step process:
STEP-0 Open your MPEG file in VDM2. On the menu tab, click VIDEO. Select FULL PROCESSING MODE. On the menu tab, click AUDIO. Select NO AUDIO. on the menu tab, click FILE. Select SAVE AS AVI.
This will transcode your MPEG source to uncompressed RGB with no audio track. This will be a huge file so make sure you have plenty of HDD space before proceeding.
STEP-1 With your MPEG source still open in VDM2, On the menu tab, click AUDIO. Select SOURCE AUDIO. Select FULL PROCESSING MODE. On the menu tab, select FILE Select SAVE WAV. This will transcode your source audio information to a separate file in WAV format.
STEP-2 Import the new AVI and WAV file into PPro. Create a new SEQUENCE. Place the new AVI file on a Timeline video track. Place the new WAV file on a Timeline audio track. Make sure each new track is "snugged" to the beginning of the Timeline. Render the Timeline. Play the Timeline to assure that synch is OK. Export the Timeline as a MOVIE to create a joined clip containing both video and audio.
I had the same problem after installing some audio software. Apparently, it forced my audio to emulated mode. I bet if you run (click start, then run) "dxdiag" your sound hardware will have a "(emulated)" tag after it. Usually, emulation happens when you move the acceleration bar all the way to the left. For me, however, even though I had the bar set to full acceleration, the emulation status persisted.
To fix this, I had to edit the registry. Click start, run, then type "regedit". Use the find command and search for "Device Presence". Four keys will pop up, (Default), Emulated, VxD, and WDM. Set WDM to 1 (I also set VxD to 1 for good measure, although I'm not sure its necessary) and reboot.
Dxdiag should now show your sound card normally (without the emulated tag) and premier should run fine. Hope this helps.
You should have an ASIO compatible driver installed. If your sound card manufacturer does not provide such a driver then Dan Isaacs recommends:
I used to have this problem sporadically in CS2. I also was using Realtek onboard sound. I installed this freeare app called ASIO4ALL and used ASIO4ALL as my sound device in Premiere instead of the Realtek driver. I never had a problem after that.
I still use ASIO4ALL in CS3 (whether necessary or not) -- if it ain't broke, right? I never tried CS3 without ASIO4ALL.
I finally found the problem. It wasn't a driver problem. It was my lack of understanding ASIO settings. I had to uncheck the audio device in the input but keep it checked in the output. If both are checked the timeline won't play. I guess I have to do a little reading so I undertsand this a bit more. I capture everything on this sytem with firewire so the input not being checked shouldn't be a problem (I hope).
