Thanks, that was it. It seems it defaults to HDMI output, when I do

	mixerctl -w outputs.select=headphones

I hear sound from audioplay.

No, just ld0. What does that mean then?

Yes. It sometimes plays for a bit, when I try to skip some seconds, it
dies.  Next try on the same file works. A different file does not work
at all (though it worked yesterday). Then the first file does not work
any longer either. I guess it doesn't set up the hardware correctly.

I saw that Raspberry OS does not support omxplayer any longer. Perhaps
that's a sign.

mpv even dumps core for me with the wav file. I guess, since omxplayer
doesn't work anyway, I'll retry with aarch64.
