Now I've checked my sound card...and outside of Avid, my audio works fine...but in my Avid Project, I cannot hear anything during playback. I can see the sample rate on the clip and I can monitor the audio on the Audio tool, but I cannot hear a thing.

Any suggestions? Its an Avid Media Compose 3.0 and I'm running it on a Vista 64bit, all the digitized footage is in PCM (MXF) format.

Also, in my audio project settings, I already have "Convert Sample Rate while Playing" to ALWAYS.

Any suggestions?

Check if MC muted your windows audio mixer.

Could you please explain in detail how your system is set up? What I want to know is: are you using any external sound device or a PCI soundcard or an onboard soundchip? What kind of monitors are you using (audio monitors, not your screen :)? Any kind of mixer attached? Simply: your whole audio "chain".

Complete system specs added to your profile could help, also.

Editarian:

I already have "Convert Sample Rate while Playing" to ALWAYS.

From my experiences I set it to "Never" because I want to know if there are mismatched  samplerates in my project and would correct it immediately. Setting it to "Always" might work while editing but can lead to unpleasent results, in the end.

Thanks for the reply.

I'm using the onboard soundchip which came with the Gigabyte Motherboard. And I'm not using any mixers or audio monitors...just plain speakers or headphones.

I usually have "Convert Sample Rate" to NEVER as well. Its just that I'm tring different things.

Afraid I am repeating myself: did you check that MC didn't mute the windows audio mixer (the monitor icon next to the clock)?

oh yeah yeah...all that I've checked.

Hmmm, does MC recognize your soundcard in the "Audio Project" settings?

Do you have the chance to test with a PCI Sounblaster card.

In HARDWARE in my Audio Project, its says

CARD - "DirectSound Audio & 1394 Audio"

PERIPHERAL - Avid OHCI

SYNC MODE - Internal

I'm not sure how to test my PCI Soundblaster card.

Try the following.  Open Avid and launch a project (any project).  Launch the audio tool and try and output tone.  If this works, try playing a clip or sequence.  You should have audio working for the rest of your session.

(I know this sounds like black magic, but I stumbled across this "fix" when I was trying to sort out issues with a Realtek chipset.  I have no idea why internally generated tone should fix a sound output problem.  It may work for you too.)

Hi, i know i'm probably late to this conversation but I just experienced this issue and found a fix for my situation.

One of my editors had made a sync map sequence of a whole day.  The audio was working for him yesterday and than suddenly stopped.  When however when he matched back to the clips, the audio would play fine.  

Apparently this happened because his sequence bacame too long for avid to handle.  

All i had to do was go into the command Palette hit "button to button reassignment" under the Play tab there is a button called "play length toggle" Take this button and place it on any button under your record source monitor (the monitor on the right of the two).  Now make sure you close the command palette.  Go back to your timeline that isn't playing the sound.  Click the new button that you just created should look like the letters "PL".  once this is highlighted you should have audio playing in your sequence again.

hope this helps.
