Hi, Iam new to pulse audio. I developed a custom driver based on ASoC. In sound settings sound card is listed with playback and capture. The mic's peak meter doesn't reflect anything even when mic is working. When I run pavucontrol, in input settings I could see the peak meter progress bar properly. Also, arecord works well at all times. I tested in Ubuntu 15.04. Please help in understanding, what I have missed ? Regards, Maruthi
