I just received a report from a user that my game was crashing unless he executed it with “Run as Administrator”. I checked the log file and saw that System::init was failing with return value FMOD_ERR_OUTPUT_INIT. (The crash was later, in my code; I was trying to create a DSP unit, which also failed, and then dereferencing that pointer without checking).
The game was built against FMOD Studio 1.03.00. Unfortunately, I don’t have much more information on the issue yet. I’ll paste my initialization code below, and I’ll update this post after I gather relevant OS and hardware information from the user.
#define FMOD_ERROR_CHECK( func ) \
ASSERT( Result == FMOD_OK ); \
if( Result != FMOD_OK ) \
{ \
PRINTF( "FMOD: " #func ": 0x%08X\n", Result ); \
}
FMOD_RESULT Result;
Result = FMOD::System_Create( &m_FMODSystem );
FMOD_ERROR_CHECK( System_Create );
uint Version = 0;
Result = m_FMODSystem->getVersion( &Version );
FMOD_ERROR_CHECK( getVersion );
ASSERT( Version >= FMOD_VERSION );
FMOD_OUTPUTTYPE FMODOutput = FMOD_OUTPUTTYPE_AUTODETECT;
Result = m_FMODSystem->getOutput( &FMODOutput );
FMOD_ERROR_CHECK( getOutput );
PRINTF( "FMOD: Default output type: 0x%08X\n", FMODOutput );
int NumDrivers = 0;
Result = m_FMODSystem->getNumDrivers( &NumDrivers );
FMOD_ERROR_CHECK( getNumDrivers );
ASSERT( NumDrivers > 0 );
if( NumDrivers <= 0 )
{
PRINTF( "FMOD: No sound drivers available.\n" );
Result = m_FMODSystem->setOutput( FMOD_OUTPUTTYPE_NOSOUND );
FMOD_ERROR_CHECK( setOutput );
}
const int MaxChannels = 1000;
Result = m_FMODSystem->init( MaxChannels, FMOD_INIT_NORMAL, NULL );
FMOD_ERROR_CHECK( init ); // (This is line 85, mentioned in the log file below)And the relevant part of the log file states:
FMOD: Default output type: 0x00000008
