I have looked at this in a general take. I got a VM installed with EL6 and ran firefox --debug. The errors seem to be [Child 3570, MediaDecoderStateMachine #1] WARNING: 7fffd72b46d0 OpenCubeb() failed to init cubeb: file /builddir/build/BUILD/firefox-78.3.0/dom/media/AudioStream.cpp, line 331 [Child 3570, MediaDecoderStateMachine #1] WARNING: Decoder=7fffd72cb400 [OnMediaSinkAudioError]: file /builddir/build/BUILD/firefox-78.3.0/dom/media/MediaDecoderStateMachine.cpp, line 3891 [Child 3570, MediaDecoderStateMachine #1] WARNING: Decoder=7fffd72cb400 Decode error: NS_ERROR_DOM_MEDIA_MEDIASINK_ERR (0x806e000b) - OnMediaSinkAudioError: file /builddir/build/BUILD/firefox-78.3.0/dom/media/MediaDecoderStateMachine.cpp, line 3470 [Child 3570, MediaDecoderStateMachine #1] WARNING: 7fffd72b4fc0 OpenCubeb() failed to init cubeb: file /builddir/build/BUILD/firefox-78.3.0/dom/media/AudioStream.cpp, line 331 [Child 3570, MediaDecoderStateMachine #1] WARNING: Decoder=7fffd6edd400 [OnMediaSinkAudioError]: file /builddir/build/BUILD/firefox-78.3.0/dom/media/MediaDecoderStateMachine.cpp, line 3891 [Child 3570, MediaDecoderStateMachine #1] WARNING: Decoder=7fffd6edd400 Decode error: NS_ERROR_DOM_MEDIA_MEDIASINK_ERR (0x806e000b) - OnMediaSinkAudioError: file /builddir/build/BUILD/firefox-78.3.0/dom/media/MediaDecoderStateMachine.cpp, line 3470 [Thread 0x7fffcdcf5700 (LWP 3638) exited] [Child 3570, MediaDecoderStateMachine #1] WARNING: 7fffd72b5160 OpenCubeb() failed to init cubeb: file /builddir/build/BUILD/firefox-78.3.0/dom/media/AudioStream.cpp, line 331 [Child 3570, MediaDecoderStateMachine #1] WARNING: Decoder=7fffd6edd400 [OnMediaSinkAudioError]: file /builddir/build/BUILD/firefox-78.3.0/dom/media/MediaDecoderStateMachine.cpp, line 3891 [Child 3570, MediaDecoderStateMachine #1] WARNING: Decoder=7fffd6edd400 Decode error: NS_ERROR_DOM_MEDIA_MEDIASINK_ERR (0x806e000b) - OnMediaSinkAudioError: file /builddir/build/BUILD/firefox-78.3.0/dom/media/MediaDecoderStateMachine.cpp, line 3470 when I try to play sounds from https://hpr.dogphilosophy.net/test/. Looking through the cpp code it looks like it is trying to initialize a pulseaudio stream and expects a much newer version of pulse than is shipped in RHEL-6. The differences in code between 68 and 78 in the cubeb module are very large and I am not sure I could debug this any further without a lot of study. Things which it does not seem to be: 1. selinux (having selinux on or off does not change anything) 2. various environment PULSE_* variables being set or unset. 3. Turning on MOZ_DISABLE_CONTENT_SANDBOX (supposedly fixed this for someone in an earlier Firefox) Sorry, the 6.10 has end of support now. If you're stuck with the 6.10, please downgrade the browser to the 68.12. |
