Thanks!

$ cat nice-music.wav | aplay -f S16_LE -r 44100 -c 2 --device="sysdefault:CARD=broadwellrt286"

runs nicely until I suspend. Upon resume, I hear nothing, with a number of

	haswell-pcm-audio haswell-pcm-audio: warning: stream is NULL, no stream to reset, ignore it.

messages appearing in dmesg. Strangely, pavucontrol then (after resume)
cannot find any suitable audio device any more.

Hope this helps,
