While running a semi-public beta test of some software using FMOD, I have received a number of reports that FMOD is not playing nice with iTunes 7 (and 6) (and vice versa). The reports vary:
From one user: "When the app is running the sound is off on my system. Tried a reboot. It doesn’t help. Example: I run iTunes, start a song, then start the app, iTunes goes silent. I only get sound back when I exit the app. The app itself is silent too." This same user also says: "I downloaded the fmod samples and of the 10 I tried only one made sound. I googled for ‘fmod audigy’ (I have a Creative Audigy 2 card) and found numerous references to people having problems." And: "I downloaded the development version 4.04.31, but it didn’t fix the problem. Like before, only the "3d" example file makes any sound."
Another user: "Your app does not co-exist with iTunes. It hates it." I don’t know what kind of sound card is on this machine.
From our internal testing: "If I have iTunes running and then start the app (or an FMOD sample), iTunes starts to stutter and play very quickly for a moment and then it goes completely silent." This is on an nVidia nForce 2 motherboard with Soundstorm playing through the SP/DIF channel. Winamp works fine without stuttering or affect the application.
I’ve noticed another posting on this (http://126.96.36.199/forum/viewtopic.php … ght=itunes), but I have to say that when push comes to shove, if someone downloads my product and it doesn’t work with iTunes, they’re not going to be uninstalling iTunes to solve the problem. Hey, I’m not an iTunes fan and use Winamp myself, but Apple has a tremendous foothold here, and people will expect iTunes and other applications to happily coexist.
So, what steps can I make to help diagnose these issues?

I was having the same problem. My iTunes was set-up to 24 bit output (which means ASIO, as directsound or mmsound are limited to 16 bit one). If QuickTime is set-up like this, then after fresh restarts it plays fine, but then soon after using FMOD (or anything else) it craps out.
Even 7.0.1 is not fixed (still happens on my machine), dunno about 188.8.131.52
As far as I know, the stuttering has nothing to do with your app or FMOD. As the previous poster stated, it’s an iTunes problem. I’ve run into the same issue of iTunes stuttering and playing back at double-speed any time another application had allocated the same audio device that iTunes was using. If I changed the audio device or driver interface (like changing it to ASIO from DirectSound) in the secondary app, the problem would stop. Upgrading to the latest iTunes version fixed the problem for me using a SoundBlaster X-Fi.
