After close and stop sound when we quickly initialising FMOD again by using “FMOD::System\_Create(&system)”, it gives an error “FMOD\_ERR\_MEMORY”. Can you please look into this issue and let me know what is going wrong? Thanks ---

[FMOD\_ERR\_MEMORY](https://www.fmod.com/resources/documentation-api?version=2.02&page=core-api-common.html#fmod_err_memory) means not enough memory or resources. In the context of `FMOD::System_Create`, this error arises if you have run out of physical memory or if you have more than 8 system objects. If you are calling System\_Create multiple times then I suspect it’s because you have more than 8 system objects, but on a memory constrained environment such as mobile it’s feasible you could be running out of physical memory. Are you calling `release()` on your system objects before attempting to create new systems with `FMOD::System_Create`? If you could please provide me with your FMOD version and a reproduction or code sample of what you are doing when the error occurs then I can look into the issue further. ---

> [@surfmike](#): > > “FMOD\_ERR\_MEMORY” Hi, I am sharing some piece of code below, some time it work and return “FMOD\_OK” but when I am quick start sound again after shut down, it doesn’t work. One more thing I want to add that “releaseSound” and “releaseSystem” doesn’t effect result at all. ``` Common_Init(&extradriverdata); /* Create a System object and initialize. */ [self releaseSound]; [self releaseSystem]; result = FMOD::System_Create(&system); //This line return “FMOD_ERR_MEMORY” if (result == FMOD_OK){ ERRCHECK(result); result = system->getVersion(&version); ERRCHECK(result); ``` FMOD\_VERSION 0x00020010 Thanks. ---

Thank you for the additional information. I haven’t been able to reproduce any errors by emulating your example, can you please include your method definitions for `releaseSound` and `releaseSystem`? One other thing I am curious about- why do you need to release and create a new System object here? Can you continue to use the existing System object without releasing it and immediately creating a new one? ---

```auto -(void)releaseSound { if(sound) { result = sound->release(); ERROR_CHECK(result); sound = 0; } } -(void)releaseSystem { if(system) { result = system->close(); ERROR_CHECK(result); result = system->release(); ERROR_CHECK(result); } } ``` Above is the whole code for `releaseSound` and `releaseSystem` functions. I need to create new system here to play set and play sound again after shut down and close. Am I doing something wrong here? ---

Are you creating a new system every time you play a sound? I am just trying to think of why you would need to release the system and then create a new one instead of storing it for the lifetime of the application and releasing it just before the application closes. Have you tried adding a short call to [sleepForTimeInterval](https://developer.apple.com/documentation/foundation/nsthread/1413673-sleepfortimeinterval?language=objc) before calling `FMOD::System_Create` and seeing if that affects the result? ---

I’m experiencing a similar issue, but there are no errors during the initialization of fmod and sound playback. Here’s my code: ```auto JNIEnv *mEnv = env; int code = 0; code = System_Create(&system_); LOGI("playAiSound-%s-%d", "System_Create", code) bool isPlaying = true; jclass cls; jmethodID methodid; const char *path_cstr = mEnv->GetStringUTFChars(path, nullptr); LOGI("playAiSound-%s", path_cstr) try { cls = (env)->FindClass("dev/keego/voice/fmodsound/bridge/SoundPlayUtil"); methodid = (env)->GetStaticMethodID(cls, "onInitSound", "()V"); (env)->CallStaticVoidMethod(cls, methodid); system_->init(32, FMOD_INIT_NORMAL, nullptr); // Create sound code = system_->createSound(path_cstr, FMOD_LOOP_NORMAL, nullptr, &sound_); LOGI("playAiSound-%s-%d", "createSound", code) if (path != nullptr) { mEnv->ReleaseStringUTFChars(path, path_cstr); } code = system_->playSound(sound_, nullptr, false, &channel_); LOGI("playAiSound-%s-%d", "playSound", code) methodid = (env)->GetStaticMethodID(cls, "onPlaySound", "()V"); (env)->CallStaticVoidMethod(cls, methodid); unsigned int length = 0; sound_->getLength(&length, FMOD_TIMEUNIT_MS); LOGI("playAiSound-%d", length) } catch (...) { LOGE("playAiSound-%s", "play error!") code = 1; goto end; } while (isPlaying) { usleep(100); channel_->isPlaying(&isPlaying); } LOGI("playAiSound-%s", "play over！") goto end; end: code = sound_->release(); LOGI("playAiSound-%s-%d", "release sound！", code); code = system_->close(); LOGI("playAiSound-%s-%d", "close system！", code); code = system_->release(); LOGI("playAiSound-%s-%d", "release system！", code); methodid = (env)->GetStaticMethodID(cls, "onComplete", "()V"); (env)->CallStaticVoidMethod(cls, methodid); return code; ``` Here’s the logcat: ```auto 2023-03-27 05:57:11.472 3890-4056 FmodSound dev.keego.voice.changer I playAiSound-System_Create-0 2023-03-27 05:57:11.472 3890-4056 FmodSound dev.keego.voice.changer I playAiSound-/storage/emulated/0/Music/VoiceChanger/1679844887938.wav 2023-03-27 05:57:11.522 3890-4056 FmodSound dev.keego.voice.changer I playAiSound-createSound-0 2023-03-27 05:57:11.522 3890-4056 FmodSound dev.keego.voice.changer I playAiSound-playSound-0 2023-03-27 05:57:11.522 3890-4056 FmodSound dev.keego.voice.changer I playAiSound-14293 2023-03-27 05:57:11.586 3890-4056 FmodSound dev.keego.voice.changer I playAiSound-play over！ 2023-03-27 05:57:11.586 3890-4056 FmodSound dev.keego.voice.changer I playAiSound-release sound！-0 2023-03-27 05:57:11.598 3890-4056 FmodSound dev.keego.voice.changer I playAiSound-close system！-0 2023-03-27 05:57:11.598 3890-4056 FmodSound dev.keego.voice.changer I playAiSound-release system！-0 ``` ````auto Upon closer inspection, my program is getting stuck in the following loop: ```cpp while (isPlaying) { usleep(100); channel_->isPlaying(&isPlaying); } ```` At this point, no sound is being played by the system. ---

Hi, @jeff_fmod @Connor_FMOD In my case, I have a sound card that connects some audio devices those numbers are more than 8. In my previous solution, I created multiple ‘system’ instance that binds a related device, however, I met ‘FMOD\_ERR\_MEMORY’. The reason you mentioned above(8 is maximum limit that fmod could support). My question is how to handle my case, if the audio device number is over 8? Any idea? ---

Hi, Unfortunately, 8 is a hard limit for FMOD systems.
