SWORD2: White noise with CoreAudio driver.

Description
Versions = 0.8.2 and 0.9.0svn Language = English Platform = Mac OS X 10.4.6
This bug occurs in various locations throughout Broken Sword 2. For example, start a new game, skip the introductory cutscene, and examine (right-click) the bookcase.
When using the CoreAudio driver, you should hear "white noise" that drowns out the music and dialogue. This doesn't happen when the QuickTime driver is selected.
Could this be a byte ordering issue, similar to bug #1374198?

I don't hear anything problematic in that spot (and I always use the CoreAudio driver, anyway). Normally, I'd say the problem is with the voice data, not the music anyway, but since you say that it goes away with the QuickTime driver... odd.

I thought the CoreAudio and QuickTime drivers were only for MIDI, but if that was the case they shouldn't make any difference for Broken Sword 2...

Indeed :-). I knew something was odd and bothering me here but I couldn't quite put my finger on it ... :-)

This might just be a random glitch on my system.
Over the last couple of weeks, I was continually experiencing the problem, and could reliably reproduce it. Then, soon after submitting this bug report, the problem occurs less frequently.
Swapping between the CoreAudio and QuickTime drivers seemed to have an effect, but if these are just for MIDI...
I'm guessing that SDL is used for non-MIDI games?

SDL is used for all digital sound, yes. There could, of course, be an endian problem in the Broken Sword 2 sound decoder, though if there is it ought to affect all the speech and all the music, since they use the same decoder. (Sound effects are different, though. They are just WAV data inside.)
There could be something going on that's corrupting the index into the speech/music files. Trying to decode the data from some random position would be likely to cause noise.
One possible reason for that could, as Fingolfin pointed out, be corrupted data files. (You'd be surprised at how often a bug report turns out to be just that.) Could you try re-copying them from your CDs, and see if that makes any difference?

I've recopied the data files from my CDs, and verified the hard disk with Disk Utility. I'll test the game over the next few days and let you know if the sound problem reoccurs.

I couldn't reproduce the bug as described in my initial comment, but the sound problem did occur elsewhere, when Nico is at the British Museum.
If the data files were corrupt, I should hear white noise every time a certain part of the game is played. So why does the problem only occur intermittently?
If no one else is experiencing this problem, you could close this item with "Works For Me".

I'm experiencing the same issue. Steps to repdroduce the problem (reliable):
1. reboot (important) 2. launch scummvm, start bs2, skip intros 3. as soon as george speaks for the first time, the white noise appears
If I quit ScummVM then and try step 2 and 3 again, everything is ok, no white noise can be heard.

I've reopened this item, so that it's visible on the bug tracker. Restarting the OS, as suggested by necroyeti, should enable others to hear the problem.

This is either a bug in the OS, or in SDL, but not in ScummVM. There is nothing we can do about it.

Are you on an intel or a PowerPC system (kinda important to know when you are talking about byte ordering issues *g*).
