Dear all,
One strange thing I noticed when debugging this issue is even "pactl list
sinks|sources short" show Bluetooth's headset sinks|sources properly.
However, "arecord -L" shows only my internal microphone (missing
Bluetooth's headset).
Am I missing something? Or the setup between Pulseaudio and ALSA is not up
correctly.
Regards,
Hieu Le.
