I'm on linux Ubuntu 9.10 and trying to get OpenAL-Soft working with portaudio, as a backend. Compilation works just fine, the output device(only one) returned by enumerating devices is 'PortAudio Software' but the program crashes when calling alcCreateContext. Anyone has any idea why does this happen? Here's the stack trace: #0 0xb7fe2430 __kernel_vsyscall() (??:??) #1 0xb7a63f75 sem_wait@@GLIBC_2.1() (/lib/tls/i686/cmov/libpthread.so.0:??) #2 0x816fa35 StartStream(s=0x829b3d0) (src/hostapi/oss/pa_unix_oss.c:1746) #3 0xb7d1ffd8 pa_reset_playback(device=0xb63bd008) (/home/adrian/OpenAL/trunk/OpenAL-Soft/Alc/portaudio.c:236) #4 0xb7d086a3 alcCreateContext(device=0xb63bd008, attrList=0x0) (/home/adrian/OpenAL/trunk/OpenAL-Soft/Alc/ALc.c:1259) #5 0x80c6767 Endeavour::Sound::OpenALSoundSystem::init() () (??:??) #6 0x80c6b1a Endeavour::Sound::OpenALSoundSystem::Instance() () (??:??) #7 0x80da645 CGameEngine::Init(char*, int, int, unsigned char, bool) () (??:??) #8 0x80ee0d2 GameStart() () (??:??) #9 0x80ee115 main() (??:??) Also, why don't i get any HW Acceleration here?
