Audio recording from source

i m new to linux.In windows while recording from external source to Audacity,sound can be monitored and software like VOICE MEETER are available but not in Manjaro linux.Item is recorded thru Pulse Audio but I cant hear the recording.

I suspect that the recorded item that cannot be monitored is likely to be a microphone or line-in audio source

Internal mic or input jacks usually have controls in ALSA for Loopback Mixing and/or playback monitoring controls for Mic/Line inputs to play audio direct to Headphone/Speaker outputs. The monitor controls are usually turned off by default.

USB interfaces usually have zero-latency monitoring to mix microphone input to headphones, usually controlled by hardware controls on the unit
Some USB microphones have headphone jack sockets for monitoring and may have hardware controls or ALSA software controls for monitoring
If a USB device does not have a headphone jack socket it cannot support direct audio monitoring

Audacity has an option in Preferences:Recording to allow software playback but the audio stream playing through Audacity and PulseAudio is delayed and not good for monitoring.
Using direct hardware connections in ALSA with no sound server would have the least amount of latency delays, but many people cannot talk over their own voice if audio is even slightly delayed
