Hi, I have a really old application that uses oss interfaces, and noticed that when attempting to run via padsp it would fail ( as opposed to with aoss ). After talking with Ford_Prefect in #pulseaudio, we narrowed down the problem to protocol-native.c Attached is a patch which allows padsp's get_sink_info call to success on the server side ( drop-invalid-check ). He mentioned that name is allowed to be null; which makes me think it might be less confusing to just do a *name check and then no others. Additionally, I noticed that in padsp.c it was recieving two callbacks in both sink and source_info_cb. As this appears to be the desired behavior in introspect.c, I modified the _cb functions to only notify if success was not already set. -drew
