Yes, this really sounds like a audio driver issue or a potential codec
issue. Especially if varies based on format via firewire. The audio is
usually processed through audio chipset. There are certain conditions like
this where the audio will also get out of sync with the video while using
firewire.
Go to the HP site and go to the support page. You can enter your model
number and get the downloads list for you computer. Download the latest
audio driver and see if it corrects your problem.
