Hi, all. My program use portaudio API. All work fine, but when I tried to route audio stream to jack by using oss2jack, at the beginning it writes: Pa_SetupDeviceFormat: HW does not support 2 channels then, when program begin to using audio channel, it crash with following message: Pa_SetupDeviceFormat: HW does not support 2 channels PaHost_WatchDogProc: killing hung audio thread! Killed Does anybody know how to use portaudio and oss2jack, or other way to route portaudio based" audio stream to jack ? PS: I can't use jacklaunch because it writes jacklaunch: line 68: 1754 Killed at start
