Troubleshooting QuickTime 6.4: USB static; GSM encoded WAV files; MPEG-2 playback

USB static Robert Hull writes "After upgrading to QuickTime 6.4, I experienced a large amount of background static when using my Onkyo MSE-U33HB usb audio adaptor. I also lost the ability to use this device as an input in Peak LE 4.0.1. Reverting to QuickTime 6.3 (see previous article for instructions) solved the problems. I have seen people on Apple's board indicate similar problems with the Griffin PowerMate so I'm led to believe that this is a general USB audio issue."

GSM encoded WAV files Kee Hinckley notes that QuickTime 6.4 appears to finally support GSM encoded WAV files. These are typically used for voice compression and voice mail system. "In particular it means that I can finally listen to messages directly in Eudora rather than having to use the sox command-line program to convert them to AIFF."

UPDATE: MPEG-2 playback We previously reported reader problems playing MPEG-2 files after updaring to QuickTime 6.4. Apple has now posted a Knowledge Base document indicating that an updated version of the MPEG-2 Playback Component is required for use with QuickTime 6.4 on Mac OS X. The article reads:

"If you purchased the MPEG-2 Playback Component from the Apple Store online or received it with Final Cut Pro 4 or DVD Studio Pro 2, you are eligible to receive an updated version for free.

Based upon how you received your copy of the MPEG-2 Playback Component, you either need to:

  • Login to the Apple store with your username and password, then go "Software Download Purchases" and download the new Playback component (individually bought MPEG-2 component), or
  • Check software update (Purchasers of Final Cut Pro or DVD Studio Pro)
