audout:u OpenAudioOut and IAudioOut (#138)
* Updated the audout:u and IAudioOut, now it might work with RetroArch without trigger an assert, however it's not the ideal implementation * Updated the audout:u and IAudioOut, now it might work with RetroArch without trigger an assert, however it's not the ideal implementation * audout:u OpenAudioOut implementation and IAudioOut cmd 1,2,3,4,5 implementation * using an enum for audio_out_state as well as changing its initialize to member initializer list * Minor fixes, added Service_Audio for LOG_*, changed PcmFormat enum to EnumClass * Minor fixes, added Service_Audio for LOG_*, changed PcmFormat enum to EnumClass * added missing Audio loggin subclass, minor fixes, clang comment breakline * Solving backend logging conflict * minor fix * Fixed duplicated Service NVDRV in backend.cpp, my bad
