Hi, As we know, pulse recognizes every sound card's source as a source and a monitor device. We use monitor device to record any activity on that sound card's source. However, for a scenario like a sound card used for making a phone call, and we wish to record the entire ongoing conversation. In that case we need to capture both the streams, the source and sink. At first I thought, If I set PULSE_SOURCE as monitor and PULSE_SINK as the sink of the sound card, and then do arecord -D default > x.wav, both channels would be recorded. However that is not happening. Kindly suggest what is the best way to do it using pulse ? Thanks -- Thank you... Amar Akshat (????)
