Hello everyone can you check this issue? Any idea on what is going on?

Thanks!

anon63346430 · January 9, 2019, 10:45pm

We all have this… it needs fixing.

It also causes wakelocks in AudioMix.

Both cause issues.

fkilius · January 10, 2019, 5:19pm

Thanks SGS, there is any workaround to avoid this error?

rob · January 10, 2019, 8:46pm

About the only immediate thing I can think for you to try is to switch to the audio2 library and see if that solves the problem.

if audio2 then &nbsp; &nbsp; audio=audio2; &nbsp; &nbsp; al=nil;&nbsp; &nbsp; &nbsp; print("=====\>\>&nbsp; &nbsp;Using audio2!!!&nbsp; &nbsp;\<\<=====") end

Note this works on Android builds only. The simulator will return nil for audio2 regardless of the skin selected. There is no al.* library with audio2, so we nill that out. You need to test thoroughly because once we addressed the common issues with OpenAL, we didn’t feel the need to pursue audio2.* any longer. But it may address your specific issue.

It’s also likely that you’re doing something specific in your code that’s causing this. A SIGSEGV/signal 11 is a segmentation fault which is Unix/Linux lingo saying that you’ve tried to access a memory location you are not allowed to access. This can commonly happen when you try to reference a resource that was deleted. I’ve seen it happen when you have an enterFrame listener running, forget to delete it, change scenes and then remove the scene. Then the enterFrame listener tries to call a function that was deleted when the scene was removed.

In the OpenAL case, perhaps you have an onComplete() triggering that’s trying to call a function in a scene that no longer exists. I can see this happening when you play a sound, change a scene, forget to stop the sound and then remove the scene. The onComplete triggers to a function that no longer exists.

Of course, its possible too since it doesn’t happen on all devices is that a bad audio decoder has shipped with some device.

anon63346430 · January 10, 2019, 8:57pm

To be fair Rob, no Corona code should ever cause a crash. The framework should always do a null check.

In my experience it is more likely to be device dependant - seemingly Android 6 is by far the worst culprit with these things.

I’m guessing what we are all asking for is some hardening in core to ensure these crashes don’t happen because there isn’t much we can do in our code to stop them.

You know my use case and that I only have a single scene and I can tell you for a fact that these errors happen even with just a single looping MP3.

fkilius · January 10, 2019, 10:05pm

Maybe this can help, the day when we start to notice this errors we released a version with some modifications in sounds usage based on the recomendations from another topic.

Here is the other topic: https://forums.coronalabs.com/topic/74589-signal-11-sigsegv-code-1-segv-maperr-libopenalso/#entry393417

Now we are using a a global class where the sounds are loaded at the begining of the program, and then we use this sounds along the entire app.

Here is the code of this global.lua file:

local M = {} print("LOADING SOUNDS !!!!!!!!!!!!!!!!!!!!!!!!!") local backgroundMusic = audio.loadStream( "sounds/menu-music.mp3" ) local tickSound = audio.loadSound( "sounds/tick.mp3" ) local function playLoadedSound(soundStream, audioPlayedHandler) local ch = audio.findFreeChannel(8) audio.setVolume( M.fxVolume, { channel=ch } ) audio.play( soundStream, { channel=ch, onComplete = audioPlayedHandler} ) end local function playMenuMusic() if( not audio.isChannelPlaying(1)) then print("MUSIC NOT PLAYING") print("MUSIC VOLUME " .. M.musicVolume) audio.setVolume( M.musicVolume, { channel=1 } ) audio.play( backgroundMusic, { channel=1, loops=-1 } ) end end local function stopMenuMusic() if( audio.isChannelPlaying(1)) then audio.fadeOut( backgroundMusic, { channel=1, time=200 } ) end end local function playTickSound() if(M.fxVolume \> 0) then playLoadedSound(tickSound) end end M.playMenuMusic = playMenuMusic M.stopMenuMusic = stopMenuMusic M.playTickSound = playTickSound return M

Later on every scene, we use this global file like this:

local composer = require( "composer" ) local scene = composer.newScene() local global = require("global") local function goToPuzzle() global.playTickSound() global.stopMenuMusic() end --here is the scene code

So, we changed one error by another? Or maybe misunderstood the way to use the sounds?

Thanks guys!

rob · January 11, 2019, 12:27am

Let me comment on a few things:

local M = {} print("LOADING SOUNDS !!!!!!!!!!!!!!!!!!!!!!!!!") local backgroundMusic = audio.loadStream( "sounds/menu-music.mp3" ) local tickSound = audio.loadSound( "sounds/tick.mp3" ) local function playLoadedSound(soundStream, audioPlayedHandler) local ch = audio.findFreeChannel(8) -- you don't test to see if audio.findFreeChannel() returned a valid channel or not. -- it's possible ch = 0 here which would be the master volume. -- -- next M.fxVolume is undefined. It should be a value of 0.0 to 1.0. I don't see where -- you're ever setting it. audio.setVolume( M.fxVolume, { channel=ch } ) -- -- You don't test that soundStream is a valid handle. If audio.loadSound() or audio.loadStream() -- fails this will likely be nil, and audio.play() is expecting a sound handle. You should -- test this: if soundStream then ... -- -- Again, channel could be 0 here. If it's zero, it should select a channel for you. -- -- You never pass an audioPlayedHandler to this function so you're always calling this with -- onComplete = nil. That should be no harm, but in case something isn't hardened further -- down the line, trying to play nil could SIGSEGV. audio.play( soundStream, { channel=ch, onComplete = audioPlayedHandler} ) end local function playMenuMusic() -- -- You want to play the music on channel 1. I don't see where you're even trying to call -- this function, but if your tick sound is playing, it could be on channel 1 which could -- cause this to not play -- -- I don't see where you're setting M.musicVolume, so you could be trying to set it on a nil -- channel value. if( not audio.isChannelPlaying(1)) then print("MUSIC NOT PLAYING") print("MUSIC VOLUME " .. M.musicVolume) audio.setVolume( M.musicVolume, { channel=1 } ) audio.play( backgroundMusic, { channel=1, loops=-1 } ) end end local function stopMenuMusic() if( audio.isChannelPlaying(1)) then audio.fadeOut( backgroundMusic, { channel=1, time=200 } ) end end -- M.fxVolume could be nil. local function playTickSound() if(M.fxVolume \> 0) then playLoadedSound(tickSound) end end M.playMenuMusic = playMenuMusic M.stopMenuMusic = stopMenuMusic M.playTickSound = playTickSound return M

Generally speaking, if you’re going to play audio on a specific channel, i.e. music on channel 1, I generally want to reserve channels, so they will be taken out of the auto channel selection pool. See audio.reserveChannels().

fkilius · January 14, 2019, 12:02pm

Hy Rob thsnks for your response, we made som changes on our code based on the recomedations that you made and released a new version. Now we have something like this:

local M = {} local backgroundMusic = audio.loadStream( "sounds/menu-music.mp3" ) local tickSound = audio.loadSound( "sounds/tick.mp3" ) audio.reserveChannels( 2 ) -- Background music uses channel 1, we reserve two channels local menuMusicChannel = 1 --the properties M.fxVolume and M.musicVolume are setted at start of the game and never have nil value local function playLoadedSound(soundStream, audioPlayedHandler) if(soundStream ~= nil) then local ch if(audioPlayedHandler == nil) then ch = audio.play( soundStream ) else ch = audio.play( soundStream, { onComplete = audioPlayedHandler} ) end if(ch \> 0) then audio.setVolume( M.fxVolume, { channel=ch } ) return ch end end end local function playLoadedMusic(soundStream, audioPlayedHandler, loops) if(soundStream ~= nil) then if(loops == nil) then loops = 0 end local ch if(audioPlayedHandler == nil) then ch = audio.play( soundStream , { loops = loops}) else ch = audio.play( soundStream, { onComplete = audioPlayedHandler, loops = loops} ) end if(ch \> 0) then audio.setVolume( M.musicVolume \* 0.8, { channel=ch } ) return ch end end end

So, now we are checking for nil values at soundstream, handler for oncomplete and also checking the assigned channel where the sound was played.

But still having the same errors and the same crash rate.

Here are the details that we have at play store:

This is our top error at list, with the highest crash rate, the others have the same error message but i dont know if they are the same or different errors.

Any additional idea to resolve this errors?

Thanks!

You might want to try the audio2 library that I mentioned higher up in the discussion.

Rob

fkilius · January 14, 2019, 7:12pm

Hello Rob, we build and deploy the app in our testing device using audio2 without luck. Some of the sounds dont play at all and the UI freezes sometimes when one of this sound does not play.

We put in mail.lua on line 1 this code:

--Replacing Audio by Audio2 to resolve signal 11 (SIGSEGV), code 1 (SEGV\_MAPERR) in libalmixer.so if audio2 then audio=audio2; al=nil; print("=====\>\> Using audio2!!! \<\<=====") end

We see in the logcat the message using audio2, so i guess this is fine. But i cant see any error on logcat about the sounds that doesnt play.

Regards

fkilius · January 18, 2019, 5:55pm

Hey guys, any other idea about this problem? Please we really need to fix it and we dont even know where is the problem.

Thanks

fkilius · March 5, 2019, 3:05pm

Hello Everyone, 2 months after first post we still having this problem and we can’t figure it out a solution.

Please we need help!

Thanks!

rob · March 5, 2019, 8:23pm

Can you produce a simple demonstration app that causes this error to happen?

Rob

fkilius · March 7, 2019, 1:55am

Hello Rob, unfortunately we cannot reproduce this error on our devices. We dont even know where or when is crashing the application because the stack trace in play console is not part of our code.

So, we know that the error is there and is causing a high crash rate, but we have no idea of where, how and why is produced.

Regards

rob · March 7, 2019, 4:33pm

Is there a particular pattern of device or OS combos these crashes are happening on?

fkilius · March 7, 2019, 5:08pm

I dont see any pattern, here are the errors in the play developer console:
