After I spent hours bisecting, I was kind of assuming you'd cc me on
merge request or something like that... so that I could test it before
going mainline. Which of those should fix it?

I tested today's mainline, and... sound fails, different way:

pavel@...0:~$ cat /proc/asound/cards
 0 [RX51           ]: RX-51 - RX-51
                       RX-51
pavel@...0:~$ cd g/tui/ofone/
pavel@...0:~/g/tui/ofone$ cd
pavel@...0:~$ festival --tts
		       ahoj
		       ^D
		       uname -a

(Festival is hung).

Let me try the revert again...
