AE won't render with audio?

Okay, i'm having this problem with rendering in AE.
I'm trying to render a simple 5 sec clip with some audio tracks, if i do it without audio checked in the output settings, everything goes fine. It renders in no time. But when i check the audio, it just stays at the first frame when rendering and does nothing. But it doesn't freeze up, everything still works. I waited for around 20 minutes, there's gotta be some problem somewhere, right?

The problem may not be your audio files, but your VIDEO files. Read on.....
Dave's Stock Answer #1:
If the footage you imported into AE is any kind of the following -- Native HDV, MPEG1, MPEG2, mp4, m2t, H.261 or H.264 -- you need to convert it to a different codec.
These kinds of footage use temporal, or interframe compression. They have keyframes at regular intervals, containing complete frame information. However, the frames in between do NOT have complete information. Interframe codecs toss out duplicated information.
In order to maintain peak rendering efficiency, AE needs complete information for each and every frame. But because these kinds of footage contain only partial information, AE freaks out, resulting in a wide variety of problems.

Well the audio format is PCM, if that's what i should be looking for here. Not really familiar with this, i tried eliminating different parts, and the audio is really the only thing seeming to cause this glitch.
I don't know, could it be in the settings? I'm using all the defaults although.

Re-read the above post. The problem may not lie in audio files, but video files.

Yeah, i've tried that, and as i've said many times, rendering without the audio everything is okay, but when i try to render audio with the comp or just as a single file, it won't start rendering. I can't seem to imagine how that is caused by any of the video files. But thank you.

I'll have another look at the files, and i'll have another go at the output settings. Yeamh, i'd be happy if it would start rendering at all and give me an error file, but it won't. I tried deleting the two video footage files before, but it didn't help if i remember correctly. But as i said, i'll give it another shot.

[Silver Adamson]"...that wouldn't help really. "
Nope. Now it's time to start looking at other things:
• Make sure the audio sample rate of your files and the AE project match, e.g. 44.1 kHz with 44.1 kHz or 48 kHz with 48 kHz.
• If you have Open GL activated, turn it off. Never mind what the Adobe propaganda says, Open GL is virtually useless in AE.
• Got any compressed audio (mp3, etc) in an audio track of a video file? Change it to wav or aiff.

Okay, a little progress, the sample rates didn't match indeed. The audio sample rates were 48 kHz, not 44 as set. But still, didn't start rendering. Open GL is turned off and all the files are .wav format.
