After managing to get Adobe to address the shockwave 11.5 compressed sounds playing at the wrong pitch, I still seem to have noticed another sound bug since updating to the 11.5 plugin.
Using Director 11 I use sound(1).member to check if a particular sound is playing in channel 1 or not each frame. Then play a new sound in that channel with puppetSound.
Since Adobe has updated to 11.5 plugin (even the latest version), The sound(1).member has a lag before it is updated correctly to the newly puppeted sound. This causes a jitter buzz in my games, as the new sound repeatedly tries to play for half a second or so, as the sound(1).member has not been updated in a timely manner.
Can anyone replicate please? This didn't occur in any previous versions of the plugin.
Known issue - reported on Direct-L a couple of times independently; see here and here. The current work-around is for you to keep track yourself of which sound you started playing until such time as the engine catches up. Hopefully this is slated for a fix, but given Adobe's opacity how would anyone know?
I submitted an Adobe bug report in case nobody else has yet. Let's hope they fix it like the sound pitch bug.
