Can't Record Computer Audio

Hey, i have recently ran into an issue with recording Audio. In specific my speaker audio. Now, i have never ran into this issue before. And i can record audio from my Microphone without any issues. That said the audio from speakers is just a flat line. Which after i amply it revealed it to be recording static.

Now, i have no idea what would be causing this. And a lot of the general fixes didn’t do anything for me. So any thoughts?

O i forgot to mention this. I am using windows 10 and the current version of audacity. I have 2 speakers, one being a headset another being a speaker, the speaker is a Logitech Z623 speaker and the headset being a JBL quantum 800.

Are you the same rman88 who just reported on discord, “o never mind now i can access it…for some weird reason
ok i made the post.” ?

OK, do Transport > Rescan Audio Devices, then try using WASAPI and your speaker (loopback) as your recording device.

Ok, i am not getting the option for Speaker(loopback).

I assume that you selected “WASAPI” as the “host” in the Device Toolbar?

Open and save the “Audio Device Info” (“Help menu > Diagnostics > Audio Device Info”), and attach it to your reply (See:

That i did. I also tested every different sound device i have. To see if their was any direct corlation between one device or another. but regardless i didn’t get any sound.

Hear is the file, and an image of the player. Just encase that helps.

So, you seem to have your choice of the following loopback devices:

U32R59x (NVIDIA High Definition Audio) (loopback)
Headset Earphone (JBL Quantum 800* Chat) (loopback)
Speakers (JBL Quantum 800* Game) (loopback)
Speakers (Realtek(R) Audio) (loopback)
Headphones (CORSAIR ST100 Headset Output) (loopback)

Be sure you have the correct loopback device selected.

Ok, i see what you meant by loopback device. as i was thinking it was in the Speaker section of audacity not in the mic.

That said, When i attempt to use JBL Quantum 800 game, Realtek(R) Audio, CORSAIR ST100 Headset Output I get, and error -9996 with the details of.

If i use NVIDIA High Definition Audio, BL Quantum 800* Chat it dose not give me the error. But the bar dose not start recording anything.

Ok, i was messing with it and somehow got it to work. I made it go on directsound, with Realtek(R) Audio on both both stereo mix and speakers. i can’t get it to work on my headset. but this seemed to fix the issue. as it is recording sounds normally.

Running Audacity v 3.0.4 Windows 10… All was working perfectly for a while and after some type of windows update I no longer can record anything that Im playing on my computer. I used to bring up an MP3 file and lay it and then bring up Audacity and click the recording icon and then I would record it. now when I click on the recording icon I don’t see any activity after the red line that moves across the screen. Thought it was an issue with the sound card and got another one since this is an old PC but same thing happens. Setting for recording device is Line In (IDT High Def Audio) and playback is Speakers (IDT High Def Audio). have tried to restore windows to earlier restore point to no avail.

Are you trying to record an MP3 file? Why not just import it directly into Audacity?

Hi. Thanks for your question.

I am actually trying to record a program from SiriusXM for example… a dj mix while they are playing it… I wrote that mp3 as an example but most of the recordings that I’m trying to capture are live streaming … also something else that may be related I have the same issue with another program that I use to do the same thing…

I was thinking this may be windows related as opposed to audacity only…but I’m guessing at this point…thanks again…

So sometimes after a windows update, you can lose “Stereo Mix”. If this is available, it can be restored by running “mmsys.cpl” from the Windows magnifying glass, then selecting the Recording Tab. Right-click on blank space in the Window and select “Show Disabled Devices”. Then select “Stereo Mix” and enable it. After doing this, do Transport > Rescan Audio Devices in Audacity.

Personally, I change MME to WASAPI, then select “Speakers/Headphones (loopback)” as my recording device.
