For this I have a jack cable that connects the piano with my laptop. My laptop has an built-in microphone that I don't want to use it when recording from my keyboard. So, I connected my piano with the laptop by jack cable. I can hear the piano sounds but Audacity records the internal microphone sounds. If I connect a microphone instead of piano, I can record the microphone sounds using Audacity. `pactl list sources` outputs this in the `Ports` section: ### Case 1 Piano is connected: analog-input-microphone-internal: Internal Microphone (priority: 8900) analog-input-microphone: Microphone (priority: 8700, not available) ### Case 2 An external microphone is connected: analog-input-microphone-internal: Internal Microphone (priority: 8900, not available) analog-input-microphone: Microphone (priority: 8700, available) How can I record the piano sounds?
