I've been able to work around most of the current bugs in SoundPool while developing a step-sequencer app, but my sticking point is stopping a non-looping sound once it's started. I've seen this code suggested here and in a few other threads as a workaround for the pause/stop bug:
mSoundPool.setLoop(soundId, 0); mSoundPool.setVolume(soundId, 0.0f, 0.0f); Does this actually work for anyone to stop a playing NON-LOOPING sound immediately? In all of my testing on the emulator and G1 it only works the first time I try to stop the playing sound, after that it seems to have no effect and logcat shows no errors. The only way I've ever been able to stop a sound is to use the above code then re- instantiate the SoundPool, which itself causes deadlock if done repeatedly and is horribly inefficient in my case anyway. I know all of this is fixed in Cupcake, but am just interested to know other's experiences in the current SoundPool implementation (especially since it's not even clear if/when T-Mobile is going to bring Cupcake to G1 owners, and I'm just plain impatient :). For anyone else struggling with SoundPool, in addition to the above these are a few points I've found through a LOT of testing: srcQuality - has no effect, use the default 0 priority - seems to have no effect, use the default 1 volume - valid values are floats 0.0 to 1.0 rate - valid values are floats 0.5 to 1.5 maxStreams - maximum concurrent streams (ie, playing a 200ms sound twice 50ms apart uses 2 streams since they overlap) setLoop()/setVolume() - if you're not looping the sound are unnecessary as you can set volume in play() pause/stop/resume - DON'T USE :) should you use it at all? - if you don't need to change pitch, personally I would suggest reading the source for SoundPool/ SoundPoolThread and creating your own implementation using MediaPlayers as others have suggested. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Developers" group.
