"Original quality" audio sync poor quality

For a long time I’ve looked forward to having lossless audio syncing. However when I enabled this with the latest beta, the audio quality is less than if it were transcoding to 320. Has anyone else had this issue? Is there a fix?

What file type / audio encoding are you trying to sync?

We found an issue with syncing certain file types with original quality audio. We’re removing the Original audio quality option from this release but it should be back in the beta after 4.6 if there aren’t further issues. Sorry!
