I'm experiencing this with a locally compiled build on macOS, revision 07484bfdb96b. Filed against cubeb because the first assertion error message appears to be there Steps to reproduce: 1) Browse to https://appear.in/ 2) "Create new room" 3) Allow access to camera/microphone 4) Crash This crashes reliably for me. I'm experiencing a full browser crash, not just the content process -- so I suspect there's actually two bugs here. What follows are the stdout/stderr from my process. (Is there a way to use the crash reporter on a local dev build?) 2017-07-25 09:53:18.097 firefox[69438:1196695] IMKInputSession presentFunctionRowItemTextInputViewWithEndpoint:completionHandler: : [self textInputContext]=0x13021d160 *NO* NSRemoteViewController to client, NSError=Error Domain=NSCocoaErrorDomain Code=4097 "connection from pid 0" UserInfo={NSDebugDescription=connection from pid 0}, com.apple.inputmethod.EmojiFunctionRowItem [Child 69443] WARNING: Cannot query channel count on a AudioSegment with no chunks.: '!mChunks.IsEmpty()', file /Users/agaynor/projects/mozilla-central/dom/media/AudioSegment.h, line 370 [Child 69443] WARNING: No audio tracks, but full-duplex audio is enabled!!!!!: file /Users/agaynor/projects/mozilla-central/dom/media/MediaStreamGraph.cpp, line 535 [Parent 69438] WARNING: NS_ENSURE_SUCCESS(rv, rv) failed with result 0x80070057: file /Users/agaynor/projects/mozilla-central/netwerk/base/nsChannelClassifier.cpp, line 316 Assertion failed: (stream_params->channels >= mixer_params->channels && mixer_params->channels > 0), function cubeb_downmix, file /Users/agaynor/projects/mozilla-central/media/libcubeb/src/cubeb_mixer.cpp, line 383.

Alex, what is your audio setup? Do you use a USB headset, or just earbuds? What version of osx is that?
Flags: needinfo?(agaynor)
This is MacBook Pro, with an external monitor (which has a camera, maybe a microphone?), and also a standard pair of headphones. This is macOS 10.12.6.
Flags: needinfo?(agaynor)
What device do you choose when you're allowing appear.in to use your microphone/camera ?
Flags: needinfo?(agaynor)
Camera: FaceTime HD Camera Microphone: default: Display Audio
Flags: needinfo?(agaynor)
I am facing a similar issue with my debug build. The good point is that I have it only with one specific headset. In my case the internal device works well. What looks strange is the callstack though. I do not expect cubeb being called from the destructor of ImageLayerComposite.
This is not the internal device, this is a screen that has a microphone. We need to fix this quickly, having assert that blow up for legitimate use cases is not great.

Paul, is there any chance someone from your team will have a chance to look at this? It's a real bummer when trying to test sandboxing changes which might impact AV :-) FWIW, even simpler reproduction with: https://www.webrtc-experiment.com/RecordRTC/

Alex, can you fix this? You said you can repro.
Flags: needinfo?(padenot)
Yes I can take it.

Thanks much!
The problem in that assert is the mixer_params->channels = 0 (mixer_params->layout = CUBEB_LAYOUT_UNDEFINED). We calculate the channels value from "global" layout here: https://searchfox.org/mozilla-central/source/media/libcubeb/src/cubeb_audiounit.cpp#415 The "global" layout is set during stream_init (in audiounit_layout_init()) after setting the stream layout: https://searchfox.org/mozilla-central/source/media/libcubeb/src/cubeb_audiounit.cpp#1408 The method above can return CUBEB_LAYOUT_UNDEFINED and that creates the error. Worth to mention that the method returns different values for the same device between a debug/release builds or between stand alone cubeb app or firefox, for the same configuration. IMO there is no point to try to mix when the mixer layout is CUBEB_LAYOUT_UNDEFINED. We need to take that into account during stream init and not to instantiate a mixer (and not attempt mixing during audio callback) when that's the case. In addition it would be nice to add mixer params in cubeb_stream struct and check them through out the call. @chunmin since you implemented most of the mixer functionality can you tell me your thoughts?

In the meantime I pushed the implementation to a branch. Feel free to comment on that too. https://github.com/kinetiknz/cubeb/pull/397
