The earlier pulseaudio log didn't show any recording streams from chrome. If you manage to get chrome to create a recording stream (you'll see it in the "Recording" tab of pavucontrol), a new log might show something, although I'm not particularly optimistic about that. To narrow down the problem further, you could try recording from the microphone at the same time when chrome is supposed to be recording from it. You can use this command: parecord --device=alsa_input.pci-0000_00_1b.0.analog-stereo test.wav When you play back that test.wav file, does it contain better microphone audio than what chrome produces? > And yes, there is an error nmessage in my terminal (please look at latest > line) > > /usr/bin/google-chrome-stable %U > [2613:2613:0215/125529.812664:ERROR:gl_surface_glx.cc(406)] glxQueryVersion > failed > [2613:2613:0215/125529.812964:ERROR:gl_initializer_x11.cc(130)] > GLSurfaceGLX::InitializeOneOff failed. > [2613:2613:0215/125529.829241:ERROR:gpu_child_thread.cc(327)] Exiting GPU > process due to errors during initialization > [2527:2561:0215/125530.039051:ERROR:browser_gpu_channel_host_factory.cc(113)] > Failed to launch GPU process. > [2527:2561:0215/125530.049017:ERROR:browser_gpu_channel_host_factory.cc(113)] > Failed to launch GPU process. > [2527:2561:0215/125530.057225:ERROR:browser_gpu_channel_host_factory.cc(113)] > Failed to launch GPU process. > [2527:2561:0215/125530.059328:ERROR:browser_gpu_channel_host_factory.cc(113)] > Failed to launch GPU process. > [2527:2561:0215/125530.061832:ERROR:browser_gpu_channel_host_factory.cc(113)] > Failed to launch GPU process. > [2527:2561:0215/125530.064292:ERROR:browser_gpu_channel_host_factory.cc(113)] > Failed to launch GPU process. > [WARNING:flash/platform/pepper/pep_module.cpp(63)] SANDBOXED > [WARNING:flash/platform/pepper/pep_module.cpp(63)] SANDBOXED > [1:23:0215/125626.008144:ERROR:audio_send_stream.cc(90)] Failed to set up > send codec state. That error doesn't unfortunately tell me much. This looks more like something that Chrome developers should look at. -- Tanu https://www.patreon.com/tanuk
