"FMOD failed to initialize ... Error initializing output device" on WP8 device

This is a big pain in my head. I have been searching everywhere about this.

The log exception that I get for my WP8 device is :

"FMOD failed to initialize ... Error initializing output device."
&
"DSP connection error. Couldn't find the DSP unit specified."

and the audio of my device gets corrupted and fails to play all types of media.

Now, Once you reset the device and install the app again, it kills device sound again. (Sometimes on the first launch and sometimes after 2-3 times)

How can I fix this issue ?

 

Bump

 

@ajketan - please don't bump a post within a couple of hours. I can see that you and @sathya share an IP. If @sathya needs help, he'll want to post more details.

 

Are you deploying in Debug mode? There has been some issues when doing this, have you tried Release or Master?

 

Master build.

 

@Graham Dunnett,
Yes i am getting the same issue with Master Build as well. Tried disabling unity audio from Project settings still same issue repeats. Tried deploying on nokia Lumia 820 and 520.
Once this happens game starts spamming logs thus making the game run really slow.
Only solution i found for this was to reset the device to its factory defaults but launching the game again makes the same issue repeat again. Attached unity log with this. please check the log and assist me fixing this issue.

 

First thing i notice is you may be missing a script?

Could you submit a bug report with a sample project and paste the case number in here too.

Edit: Moved to Windows Development as it's platform specific.

 

Somehow in audio settings DSPBuffer size was set to "Best Performance". Reverted it back to default and it solved the issue. Thanks.

 

No this issue started showing up again

 

Sorry to necro but I just ran into this issue trying to build today at the Unity 5 Roadshow with Unity5.0.2... Upgrading to Unit 5.1 fixed this issue for me

 

This is possibly an issue with the AudioSrv service in Windows. Go to the TaskManager. Go to the Services tab. Find 'AudioSrv' in the list, right click and Restart it. Then restart Unity. Should fix it.

 

I am having this error "FMOD instantiation failed" and I have attached a screenshot please try to fix it for me

 

This issue had not occurred before, simply appeared when I started Unity while working through the Tanks tutorial. I restarted Audiosrv before I tried any other fixes, and the problem was solved. Technology is weird.

 

I removed from scene SoundSource with AudioClip located in Resources folder, reboot computer and it works brilliant. Do not hold clip which is referenced by SoundSorce in Resources or it children, move it to other folder.

 

I had the same error when i played with playback devices properties.
Solved it this way:
1. Open current sound playback device properties.
2. In enhancement tab, switched back to immediate mode.
3. Solved. No fmod error. And in game sound working.

 

tengo el mismo problema de
FMOD failed to initialize the output device, attempting to initialize the null output.
ya no se que hacer intente todo lo de aqui, pero nada
