FCPX + Lion + Cannot handle AAC or Apple Lossless audio in H.264! (Clicks and Pops)

(So first of all I tried all of this on a MBP on Snow Leopard and didn't run into these issues.) What the video is showing is how FCPX in Lion cannot handle compressed audio, especially AAC and Apple Lossless. Linear PCM (like Canon's H.264 DSLR movie files) or uncompressed audio is fine, and so are MP3s apparently (did a test just with MP3s and WAVs and AIFFs and it all came out fine). Now FCPX will export as H.264 (which its codec compresses the audio using AAC), however, if you then import this new footage, FCPX produces many audible clicks and pops, especially apparent if you then export it. Why is this important? For example, lots of footage can come to us already being encoded as AAC, like the iPhone 4 for example. It's H.264, but encoded as AAC. So until Apple provides a fix, it seems if we're gonna use any H.264 AAC video in FCPX with Lion, we're gonna have to somehow rip the audio out beforehand and convert it to a WAV, AIFF, or MP3, then align it back up. Very tedious. Please let me know if anybody else is having this same issue...

The Daily Mail
It is the main reason music collectors steer clear of iTunes. Now Apple is set to reverse its reputation for selling compressed music with compromised sound on its digital media player. It today emerged the company is in talks with record labels to offer greatly improved sound quality on iTunes....
Apple Lossless
| Name | Apple Lossless |
|---|---|
| Extension | .m4a |
| Owner | Apple Inc. |
| Type | Lossless audio file format |
| Contained by | MPEG-4 Part 14 |
Apple Lossless data is stored within an MP4 container with the filename extension .m4a – this extension is also used by Apple for AAC audio data in an MP4 container (same container, different audio encoding). However, Apple Lossless is not a variant of AAC (which is a lossy format), but rather a distinct lossless format that uses linear prediction similar to other lossless codecs such as FLAC and Shorten. All current iPods and iPhones can play Apple Lossless–encoded files. It does not use any digital rights management (DRM) scheme, but by the nature of the container, it is thought that DRM could be applied to ALAC much the same way it can with other files in QuickTime containers.
Apple claims that audio files compressed with its lossless codec will use up "about half the storage space" that the uncompressed data would require. Testers using a selection of music have found that compressed files are about 40% to 60% the size of the originals depending on the kind of music, similar to other lossless formats. Furthermore, the speed at which it can be decoded makes it useful for a limited-power device such as the iPod.
The Apple Lossless Encoder was introduced into Mac OS X' Core Audio framework on April 28, 2004 together with the QuickTime 6.5.1 update, and thus available in iTunes as of version 4.5 and above. The codec is also used in the AirPort Express's AirPlay implementation.
Other players
David Hammerton and Cody Brocious have analyzed and decoded this codec without any documents on the format. On March 5, 2005, Hammerton published a simple open source decoder in the programming language C on the basis of the reverse engineering work.The open source library libavcodec incorporates both a decoder and an encoder for Apple Lossless format which means that media players based on that library, including VLC media player and MPlayer, are able to play Apple Lossless files. The library was subsequently optimized for ARM processors and included in Rockbox.
