For playback there are two ports, one on transmitter aka TX and one on receiver aka RX. For Tx we use source port, and Rx uses sink ports. I should probably add port to make people really figure out we are talking about ports! So: Playback maps to source port on the TX and sink port on Rx. Vice-versa for Capture. Do you agree to above statement? -- ~Vinod _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
