The Bugbug bot thinks this bug should belong to the 'Core::WebRTC: Audio/Video' component, and is moving the bug to that component. Please revert this change in case you think the bot is wrong.

Component: Untriaged → WebRTC: Audio/Video

Product: Firefox → Core

Thanks georg for the detailed report! I'm not able to reproduce on my MBP. Does it reproduce for you here (please use headphones to avoid feedback)?

Also georg, do you happen to know if this used to work better in an earlier version of Firefox? If so, since I'm not able to reproduce here, if you would be able to run the MozRegression tool to find a regression range that would help narrow this down quickly.

Hey Jan, thanks for the response.
I am not able to repoduce via this jsfiddle. I quickly checked if anything changed with autoGainControl on and it didn't either

I am pretty sure this is not new. I jumped back to firefox as my daily driver in January (don't remember the exact date) and had problems ever since. I initially blamed the os, but since then was able to figure out that it only reproduces in Firefox. I am using Brave for audio calls for now.

I hope to do the regression tonight

Additionally, what kind of microphone are you using? I have a branch locally where this is fixed (I'm pretty sure), hoping to get this landed in the next few days, if you could have a quick try (looks like it's just a couple of minutes for you), it would be amazing. I'll let you know.

I am pretty sure it's totally microphone independent. I was able to reproduce with:

The internal macbook microphone
bose QC 2 microphone connected via bluetooth
An external microphone connected via USB

They all have in common that performance degrades around 40s into use and resets after I switch the system microphone, independently from which to which source I switch. The switching itself seems to cause the reset in quality.

Sure, very happy to test whenever you got a fix ready

You're not supposed to build anything, we have everything already built for you in a nice set of programs, see https://mozilla.github.io/mozregression/.

I'm still working on the fix, lots of moving pieces, sorry about that.

I am using mozregression. I assumed it builds locally, but now I understand it just downloads the prebuilt executables. Still, the versions of firefox I ran with it all crash on microphone activation.

No worries, as I have a mitigation by using another browser for audio, I don't need a quick fix. Thanks for working on it!

Would you mind recording a profile (instructions here in video and text: https://blog.paul.cx/post/profiling-firefox-real-time-media-workloads/#the-new-solution, it's really really simple) of more or less the same scenario you do when you record the files you attached here?

I've received an M1 Max yesterday, and audio is perfectly clear whenever I use https://online-voice-recorder.com or anything else that uses the mic, and so is on all other M1 or x86 macs I've tested (apart from the issue fixed in bug 1739505), so I'm trying to figure out what's off here.

Absolutely. This is the profile: https://share.firefox.dev/388dN4o
I will also attach the exact audio file I recorded while capturing the profile.

Georg, this is not a media profile, this is a regular profile, so unfortunately the profiler didn't profile the threads I need to diagnose this, make sure to select "Media" in the dropdown.

We're in the process of making additional fixes to the input/output audio handling, should be ready by tomorrow or so.

Downgrading because afaik this only affects one person (unlike the other bug), but we'll get this fixed anyways.

So I should repeat the profiling process, wth the media preset this time, in Firefox Nightly, right?

Hi georg, do you have a device that shows "X ins / Y outs" in "Audio MIDI Setup", where X and Y is not zero (e.g., my Plantronics. Audio 628 USB headset shows "2 ins / 2 outs")? If you have this kind of device, can you still hear the noise if you set it to your "system default output device" and choose it as the microphone? Can you test the audio on the website below?

We will do some custom settings if input and output are from different devices on "Audio MIDI Setup", e.g. my Bose QC 35 II shows "1 ins / 0 outs" and "0 ins / 2 outs", or my MacBook Pro has "0 ins / 2 outs" built-in speaker and "1 ins / 0 outs" built-in microphone. I am trying to figure out if the problem is caused by our custom settings or not.

Hey,
I do have the QC 35 II and they show up as you describe in the Audio Midi Setup: "1 ins / 0 outs" and "0 ins / 2 outs"

It indeed seems like the noise appearing is associated to the output device, no the input device.
I just tested on the https://webrtc.github.io/samples/src/content/devices/input-output/ website.
If I output to the QC 35 II, the noise starts appearing like before, around 50 seconds from the start of the use of the microphone.
It happens with both microphones, both internal and of the QC 35 II, but only if I output to the speakers of the headphones.

I can only reproduce this in Firefox, btw. The same is not true eg in Brave Browser.

If not, I've finally landed a way to get logs for this and share them easily, here's how it works:

Navigate to https://profiler.firefox.com, click the button to enable the profiler button, select the preset called "Media"
Reproduce this, on Firefox Nightly (for now, this will be available everywhere in a few weeks)
While the audio is bad, open a new tab, navigate to about:networking, click on the Logging tab on the left, and put cubeb:5 in the box Current Log Modules, click the button Set log modules
Take a profile, by clicking the profiler icon
After some time (say, 10s, with bad audio), click the profiler button again to end profiling, and capture the profile
After some time, this will open a new tab with the Firefox Profiler interface, click share on the top-right, make sure to include hidden threads (it's enabled by default), and share the URL here (or privately at <padenot@mozilla.com>, there is a way to download the profile, to e.g. attach it to an email).

Some people prefer videos, so I've recorded a screencast of the procedure here: https://paul.cx/public/cubeb-logging.webm, it's a bit longer than a minute and shows the procedure on https://mozilla.github.io/webrtc-landing/gum_test.html, which is a very simple website similar to the https://webrtc.github.io links above, but please use any website on which you can reproduce the issue.

Hey Paul, Jan,

I downloaded the latest Nightly. Unfortunately, the issue is still there. Still, for me it only happens in firefox, and only with either input or output device being different from the built-in ones (macbook mic or speakers).

I tried to follow all the steps to the point. Please let me know if it worked: https://share.firefox.dev/3CYAyVh

Thanks for still trying to fix this.

Best

Hi,
I'm facing this exact same issue on my MBA as well.

FF is my daily driver for years. Right now, I've 2 macs :

My old MBP A1989 (Core i5 - 16 GB)
My new MBA A2337 (M1 - 16 GB)

Both runs Ventura 13.0.1 and FF107-64. My headset is an AirPod Max.
