The Bugbug bot thinks this bug should belong to the 'Core::Audio/Video: Playback' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Maybe a media format issue, or some sort of device specific problem in cubeb. Mathew what are the potential causes of a failed call to CubebUtils::CubebStreamInit?

I can also confirm this bug in 115.4.0esr (64-bit), as shipped in Debian 12. This did not occur with 102.15.1esr, to the best of my knowledge.
I had seemingly identical symptoms, no sound and
[MediaDecoderStateMachine #1] WARNING: OpenCubeb() failed to init cubeb: file ./dom/media/AudioStream.cpp:281
would appear each time a page tried to play audio. about:support correctly listed my audio device along with the expected backend.
Quick disclaimer, which may not be true for the reporter: My system is an ALSA-only system, no Pipewire or PulseAudio.
In my case, about:support was full of "Rejected System Calls" for syscall 220, which was a hint.
Running with MOZ_LOG=cubeb:5, I also saw seccomp warnings repeated quite frequently.
Sandbox: seccomp sandbox violation: pid 89629, tid 89805, syscall 220, args 65543 139974933195068 2 0 8 0.
I was able to workaround this by adding 220 to about:config's security.sandbox.content.syscall_whitelist. Sound immediately worked after doing so. Removing it from a running session did not seem to have an impact, so it's possible that syscall is only needed on sound initialization.
