[openal] OpenAL soft on win32: AL lib: (EE) ALCmmdevPlayback_open: Device init failed: 0x80004005

[Lex]

You're right:
AL lib: (WW) ALCmmdevPlayback_open: Failed to find device name matching "R"

Full output goes bellow my signature just in case. There you can see 
device names as OpenAl Soft sees them.

So, I have Russian localization of Windows and therefore device names 
come with Cyrillic in them, which goes out as a garbage. So that nails 
down the problem to be either OpenAL not returning the names correctly 
or CAudio (openal c++ wrapper library) not handling them appropriately.

Excert from CAudio sources getting device names:

         if (specifier != 0 && defaultDevice != 0)
         {
             const char* deviceList = alcGetString(NULL, specifier);
             if (deviceList)
             {
                 while(*deviceList)
                 {
                     cAudioString device(fromUTF8(deviceList));
                     AvailableDevices.push_back(device);
                     deviceList += strlen(deviceList) + 1;
                 }
             }

The question why the problem is not permanent is still open.
