Audio playback doesn't work in selenoid/firefox:85+ because of "OpenCubeb() failed to init cubeb" #468

Hello. We have audio playback as part of one of our test suites. Audio playback works fine in real browsers(chrome and firefox), it also works fine in selenoid/chrome container. Previously we used selenoid/firefox:83.0 and audio worked fine too. Recently we switched to latest selenoid.firefox:93.0 and our test started to fail because audio playback fails. Log of selenoid/firefox container has "OpenCubeb() failed to init cubeb" error

I've compared older versions, and found what playback was broken in selenoid/firefox:85.0 It may be related with migratin to ubuntu20.04 as base for selenoid/firefox:85+

please use attached sample project for observe issue, you will need Java for lauch it audio playback issue.zip

Steps: 1) Run selenoid/firefox image localy, as following

docker run -it --network host --rm --privileged -p 4444:4444 selenoid/firefox:83.0 2) Run tests from attached project as ./gradlew clean test 3) Examine console output of selenide/firefox container and screenshot from test (saved to build/reports/tests)

As you can see from screenshots playback was started in selenoid/firefox:83.0 and selenoid/firefox:84.0, but was not started in selenoid/firefox:85.0

Log for selenoid/firefox:83.0 has no any error, playback is working here container log 83.txt duringPlayback_83

Log for selenoid/firefox:84.0 has E: [pulseaudio] client-conf-x11.c: xcb_connection_has_error() returned true but playback is working here, not sure if this error is important container log 84.txt duringPlayback_84

Log for selenoid/firefox:85.0 has following errors

audio playback doesn't work here (see screenshot, seeker is still in the start of progress bar) container log 85.txt duringPlayback_85

Can you please suggest something. Thanks in advance.

@bardadymovd probably a missing codec package. What kind of codec are you using?

bardadymovd commented 2 years ago

@vania-pooh we use mp3 and wav formats. answer for media request has 'Content-Type: audio/mpeg' header internal logs from player, not sure it it helps

Media used in sample test is also mp3 with "Content-Type: audio/mpeg" https://www.soundhelix.com/examples/mp3/SoundHelix-Song-1.mp3
