[linux-audio-user] jack and portaudio

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
