Avid XDcam proxy audio issues

I work with an Avid Adrenaline and a Media Composer.
I shoot everything on XDCam, standard definition.
When importing low res proxy files from disc for off-line with a Sony PDW- F70 deck, the proxy audio is obviously not 48k and has a lower quality sound, when playyed back in Avid.
This low res audio is resistant to EQ changes too.
Is there a setting to allow me to import my proxy field footage, but have the hi res audio be linked to it.
I want this because upon importing every sequence at 1:1, the audio must be checked and mixed again. If the high res audio is in the Avid upon the initial low res proxy import, i would save a lot of time. I never had this issue when digitizing from tapes at low res.

I believe the XDCam Proxy audio is 8k - in Import settings there is a check box under the XDCam tab to choose whether or not the proxy audio is converted to the project sample rate or not.
I have only limited experience working with XDCam so it may not be what you're looking for but I thought it might help.

I've made a (windows) util that rips the audio from XDcam and saves it as a multichannel BWF file that can be relinked to the proxy video. It's not on my site yet but will be there in a few days.
That could be usefull to you, but it has a downside.
XDcam is SLOW. The audio is multiplexed (meaning, video and audio are in the same file), thus to extract it my app. has to read trough the entire file, making it only a bit faster than an Avid import.
So it's only really usefull if you have a second machine to run it on, freeing your edit suite.
If you have time to spare, there is another solution.
Import the proxy with audio.
Import the high res video with audio
Trash the proxy audio channels
Trash the high res video channels
Select the proxies and do a Relink
Trash the high res Master clips (but LEAVE the audio)
Mail me if you like to toy with the XDcamToBWF util
