Crackling audio, particularly BGM but perhaps also effects

Having just purchased the game, I fired up the latest Mac beta yesterday and noticed while playing through the first bits of the game that the audio, particularly the BGM but perhaps also the sound effects, was crackling. No other apps were running at the time (aside from the standard bits of the operating system, of course), and the game was otherwise behaving fine. The crackling itself was quite subtle, not any harsh glitching or anything like that, but annoying enough to notice and detract from the experience.

If anyone else has run into this with Frozen Synapse and has some suggestions I'd appreciate them.

For the Mode 7 folks, here are some minimal system details: MacBook Air with 2.13 GHz C2D, 4GB RAM, SSD, OS X 10.6.7.
The game was running full-screen at the native resolution of 1440x900 (x32).
No peripherals attached.
Running on battery.

If you would like more detail, more specific testing, etc. let me know and I'll help out where I can.

Hi djjd42.

Please delete frozensynapse/openal32.dll, and rename wrapoal.dll to openal32.dll - this should fix your problems.

Thanks,
Ian

Thanks for the tip. I was tied up with other things today but I'll see how the game runs during my commute tomorrow and will give that change a try.

Sorry it took so long to get back to you on this, but I ended up playing without sound to avoid carrying headphones during my commute this week and only this morning cranked FS up with sound to see if I could see if your recommended fix works.

(As a reminder from my first post, just in case it is relevant given the fact that you've asked me to rename .dll files: this is all on OSX.)

I've browsed around in the FrozenSynapse folder and even cracked open the .app bundle and took a look in the folders within. I definitely found some files related to OpenAL, but only because you seem to have included source files in your distributed .app bundle for some reason, and I haven't seen anything related to "openal32.dll" or "wrapoal.dll" so far. I hate to ask a potentially stupid question, but where are these two files located?

Any assistance you could provide would be greatly appreciated, as in the meantime I'm generally resorting to playing without sound and, as much as sound is not 100% essential in a game like FS, I do miss the nice music and sound effects. :)

Hi djjd42.

I believe this issue is fiex with the latest OSX build - can you redownload it and tell me if it is not?

Thanks,
Ian

I am using windows 7 64-bit with an x-fi titanium sound card and I am also having this issue. From time to time, the music gives a crackling sound. It is irritating. I have a steam version and there is no wrapoal.dll.

Yeah, it was experimental at best. I too got the weird distortion on android with low latency audio enabled, but it was significantly reduced without low latency audio.
