I'm confused. Shouldn't the in-game movies and instructions have speech? I'm only getting subtitles, and the occasional "bong" sound. The instructional movies also make a "click" at the start and end, and a hiss while they play through.
The startup movie has sound, so I'm guessing this is something lost in the audio codec.
I've done an update [edit: and reboot], followed by "git reset --hard c1cbf05 && git clean -f" as root in the "~/piper/" directory, and another update which it claimed wasn't necessary. [edit: after rebooting again, it wanted to update again, so we wait again ... later: two updates in a row now? This is getting silly, and I have a very annoyed child waiting on this. Much later: phantom update, nothing to do but wait again. Back into his game, no change. Bonks and beeps, but no typical Minecraft sounds like footsteps, TNT explosions, etc. And still no speech, just subtitles. Let's hope there's still a problem to be fixed, because this isn't what I was expecting.]
What else is there to check, please? Or isn't there any speech?
