Bug Failed to get number of drivers

When I start up Unity I get this error in the console:

 

Do you have PulseAudio installed and enabled? Sound doesn't seem to work without it.

Edit: Check if PulseAudio is running with pulseaudio --status

 

I get this message:

pulseaudio: unrecognized option '--status'

 

@The Little Guy ..

To check if pulseaudio is running you can do either

ps -e | grep pulseaudio , and see if it finds the daemon process , or you can do

pulseaudio --check; echo $?

echo $? shows you the exit status of the previous command, and pulseaudio --check will exit 0 if pa is running for the current user, according to the manpage. In other words if you get a 0 on the console you know pulseaudio is running.

 

@kborch

I get an exit code of "1" I tried starting it, but it didn't start

 

@The Little Guy

Ok, do you get some errors on the console then?

Did you try like this: pulseaudio

Or like this: pulseaudio --start

Or both?

Did it complete by itself or hang when you tried?

 

actually I did it like this:

sudo service pulseaudio start

doing this worked though:

pulseaudio

pulseaudio --start

Started the service

 

After restarting Unity, my driver issue is gone!

I get this message though (which I was getting before):

 

Congrats!

Perhaps mark this as solved then.

kLargestEditorClassID == ms_MaxClassID

^^ I get this error as well but only once on startup, as far as I can tell

 

Unfortunately this is also happening in the Linux standalone builds. Especially problematic when running a headless build on a dedicated server which obviously won't run any audio stuff.
At startup:

Code (csharp):

1.  
2. NullGfxDevice:
3.     Version:  NULL 1.0 [1.0]
4.     Renderer: Null Device
5.     Vendor:   Unity Technologies
6. FMOD failed to get number of drivers ... An error occured that wasn't supposed to.  Contact support.

After assemblies have been loaded:

Code (csharp):

1.  
2. Platform assembly: /home/sdtd/engine/7DaysToDieServer_Data/Managed/Boo.Lang.dll (this message is harmless)
3. Error: Cannot create FMOD::Sound instance for resource sharedassets0.resource, (An invalid object handle was used. )
4.  
5. (Filename:  Line: 858)
6.  
7. Function SoundHandle::Instance::~Instance() may only be called from main thread!
8.  
9. (Filename:  Line: 25)
10.  
11. Unable to enable tracing: Invalid argument
12.  
13. (Filename:  Line: 1323)
14.  
15. Error: Cannot create FMOD::Sound instance for resource sharedassets0.resource, (An invalid object handle was used. )
16.  
17. (Filename:  Line: 858)
18.  
19. Function SoundHandle::Instance::~Instance() may only be called from main thread!
20.  
21. (Filename:  Line: 25)
22.  
23. Unable to enable tracing: Invalid argument
24.  
25. (Filename:  Line: 1323)
26.  
27. Error: Cannot create FMOD::Sound instance for resource sharedassets0.resource, (An invalid object handle was used. )
28.  
29. (Filename:  Line: 858)
30.  
31. Function SoundHandle::Instance::~Instance() may only be called from main thread!
32.  

(And so on)

Also sometimes later on:

Code (csharp):

1. Error: Cannot create FMOD::Sound instance for resource resources.resource, (An invalid object handle was used. )

Does not seem to affect the server so far but also didn't do any stress tests as this is currently an internal only build. Same as with shaders and stuff: Why does the headless build have to even initialize this stuff?

Thanks
On my machine it's only libpulseaudio that's installed, but I suppose that's what you mean by "available"

 

Yeah, it's a 5.3.3p2 build, so that explains why it's doing that

 

I have similar issue on Android, when building with “split obb” option. In runtime application freezes instead of starting OBB download:

Code (csharp):

1. E/Unity(8332): Error: Cannot create FMOD::Sound instance for resource sharedassets0.resource, (File not found. )
2. E/Unity(8332):
3. E/Unity(8332): (Filename:  Line: 858)
4. E/Unity(8332): Function SoundHandle::Instance::~Instance() may only be called from main thread!
