When running Google Chrome from within a toolbox (currently not available as a flatpak) I can run most things just fine. However, when I try to use Google Meet or other video conferencing sites, these fail to access the microphone even after I have granted permissions to the browser. I don’t have similar issues with the video on my USB web camera. BlueJeans - as an example - reports a “Permission denied” error for the microphone when running within the Chrome browser.
Running SB 31 on a MacBook Pro (mid-2015 edition).
Let’s start by verifying your mic actually works inside the toolbox: toolbox enter sudo dnf install alsa-utils arecord -d 3 /tmp/mic.wav && aplay /tmp/mic.wav
The latter will probably fail similarly to this: ALSA lib pcm_dmix.c:1089:(snd_pcm_dmix_open) unable to open slave
This is related to Issue #58 on Github.
You may need to bind mount /dev/snd for this to work.
In the above test, merely installing pulseaudio-utils (inside the container) got aplay working.
I’m using google chrome from within toolbox (just for specific cases where I need flash) and I have this in my container Buildahfile:
# Grab Chrome Browser for multimedia playback because media codecs
# aren't in the Firefox flatpak: https://discussion.fedoraproject.org/t/flatpaks-and-media-codecs/1086/36
# Install with --noscripts because there is a bunch of junk in the scriptlets
buildah run $ctr -- bash <<EOF
