PulseAudio comes with a module that can be used to perform acoustic echo cancellation of the microphone input, and some background noise reduction. One of those options will read, "Monitor of <Internal Sound Card>". PulseAudio via GUI: Pavucontrol (Note: this is not an alphabet post. Application path: C:\pulse\pulseaudio.exe Startup directory: C:\pulse Arguments: -F C:\pulse\config.pa --exit-idle-time=-1 Service name (should be automatically filled when the NSSM dialog opens): PulseAudio In the Arguments field we're using -F, which tells PulseAudio to run the specified script on startup, while --exit-idle-time=-1 disables the option to terminate the daemon after a number . The PulseAudio line has continued to expand to include easy-to-integrate amplifiers and audio distribution solutions such as streaming receivers, audio signal extenders and converters, speaker selectors, and volume controls. Whenever I start in EchoCancellationWithSourcesMix mode, my microphone ends up being heard in my headphones and nothing is recorded from the main source, ever. Let's say I have a input: INPUT='alsa_input.usb-mic-00-mic.analog-stereo' And a filter: I'm a very late adopter for PulseAudio.

Audio recording and playback works fine in Audacity. You can make the PulseAudio settings permanent by following these instructions to put them in your default.pa file. For every sink you create, pulseaudio will also create a monitor source, so in addition to your MySink output device, you will have a MySink.monitor input device that you can use to capture what is sent to your virtual output. info: pulse-input: Started recording from 'alsa_output.pci-0000_00_1f.3.analog-stereo.monitor' info: [Loaded global audio device]: 'Desktop Audio' info: pulse-input: Server name: 'pulseaudio 13.99.1' info: pulse-input: Audio format: s16le, 44100 Hz, 2 channels info: pulse-input: Started recording from 'alsa_input.pci-0000_00_1f.3.analog-stereo . "Monitor of Built-in Audio Analog . So there is really no indiscretion that the input sources between ALSA and Pulseaudio may not match up exactly, Pulse can create audio sources not directly available to ALSA and may not use all of the ALSA sources itself. PulseAudio manages all input and output streams of all desktop applications, providing them such features as clocking, buffering, and rewinding. The sounds in your applications passes through PulseAudio. This library provides an Python 3 asyncio interface on top of the pulsectl library for monitoring and controlling the PulseAudio sound server.. pulsectl is a Python ctypes wrapper of the PulseAudio client C library libpulse, providing a high-level interface to PulseAudio's source/sink/stream handling and volume mixing.It has originally been forked from the internal code of . pacmd list-source-outputs If you unplug just the headphone jack for your headset, and leave audio playing within system but inaudible, does the microphone source alsa_input.pci-0000_0a_00.3.analog-stereo still show desktop audio playing in pagraphcontrol or does it stop ?. This requires the use of new utilities and experimentation. I don't know how to list the current default source and sink, so I use following command to verify: Basically it acts like a non-single GPU passthrough but when I shut down the guest I get the GPU back on host. It works like a proxy. So far I haven't found any errors, but I can not hear any audio from the VM in the host or any input in the VM. Open sidebar. If the application you want to record is playing to a pulseaudio then waveinput should use a pulse audio monitor device such as "alsa_output.pci-0000_00_1b..analog-stereo.monitor" and use parecord in the conf file From your description I tiunk you are mainly using pulseaudio appl;ication so first find the relevant monitor device. Pulseaudio can use ALSA input sources (among others), but can also create virtual input/output sources and interconnect them. Python (3.x and 2.x) blocking high-level interface and ctypes-based bindings for PulseAudio (libpulse), to use in a simple synchronous code.
