GetFreeChannel counted down with an unsigned loop variable, so i >= 0 was always true. With every channel already reserved it wrapped past zero and kept indexing g_audioChans until it walked off the end - sceAudioChReserve(-1, ...) segfaulted the emulator instead of returning "no channels available". Reproduces on audio/sceaudio/reserve, which crashed before printing anything. Also gives sceVaudioChReserve the parameter checks it never had. It took any sample count, channel count and frequency; the hardware allows 256, 1024 or 2048 samples, stereo only, and the same sample rates the SRC channel accepts. Every value in the test now matches - what's left there is only reschedule markers.
