I don't know if the current audio system supports more than 2 channels. There is a knob in uaudio.c that you can tune: static u_int8_t uaudio_default_channels =3D 2; But you probably have to add some code to tell the upper sound layers that= =20 there is more than 2 channels! > > PS : Do you know when these drivers will be included in Freebsd ? > I hoped before 7.0 was out, but it might be later. I am not the one decidin= g=20 that. But if many people like you turn up and tell the list how much faster= =20 and how much more solid the new USB stack is, then it might happen faster ;= =2D) =2D-HPS
