Hi All, I have observed strange behavior of PulseAudio8.0 which is as:- I have one card which have 2 devices AMIC and DMIC. I am using ALSA, UCM config files with PulseAudio. Before pulseaudio boots up Headset and DMIC have been connected on card. When PulseAudio boots up it initializes AMIC ( Headset ) only and i can record using it. Now, the problem starts. When i plugged Headset the Port switching done from AMIC to DMIC and after sometime i got overrun without recording anything. My analysis:- PulseAudio should initialize both AMIC and DMIC ( setting hw params and other stuff ) but only AMIC initialized. Only port switching should not have been happened as no hw params setup for DMIC. Port switched but PulseAudio is expecting I/P for AMIC. Am i right here? Waiting for Reply.
