I am also experiencing audio problems despite clearing my cache. And I am currently using Google Chrome.
To clarify what exactly I am experiencing, if an object plays a sound, then all other objects will be unable to play that sound until it ends. Say that there are two enemies that are supposed to play the “damage 1” sound effect whenever they get injured. In the past, if I made an attack that hit the first enemy, then the second enemy 0.5 seconds later, both enemies would play the “damage 1” sound. But now, if I were to repeat this same scenario, only the first enemy would play the sound effect, while the other enemy will be completely mute.
It also prevents an object from playing the same sound multiple times. Say that the player decides to do 3 consecutive jumps, similar to the recipe to performing the triple jump in Super Mario. Normally, each time the player jumped, a jump sound effect would play out with each jump. But now, the audio would only play on the first jump, and wouldn’t play during the other two jumps. It would just be dead silent.
There is one last audio issue that I have been experiencing. The Sound Effect Behavior will stop previewing audio entirely if that audio has already been played during playtesting. Even if you shift the volume, change the sound effect, or use another Sound Effect Behavior (whether it is new or not), the audio will not be previewed.
I’ve already tried clearing my browser cache and cookies, and the problem still shows up.
