Oh and I'm not sure off the top of my head why ERR_ACCESS would be returned as I'd likely have to pick through some code to have a proper look! That said, I think you can ignore the whole thing and not worry about it :D Cheers Col Hi Col Thanks for the reply. I had not got the design of a sink having a list of streams. Changing the code to use the pa_context_get_sink_input_info to get current volumes for all channels in stream and then setting the volume using pa_context_set_sink_input_volume() silved the problem. My best gees for the PA_ERR_ACCESS is that only one context was used for all stream/server/sink control.
