	$ aplay /usr/share/sounds/pop.wav
	Playing WAVE '/usr/share/sounds/pop.wav' : Signed 16 bit Little Endian,
	Rate 44100 Hz, Mono
[the sound is heard]
[Fn+Suspend is pressed, the laptop goes to sleep]
[Fn is pressed, the laptop wakes up]
[Same command is attempted, same output, but no sound is heard during
the pause. alsamixer shows enabled volume levels for the relevant
channels, so it looks like it's not a mixer restore problem. ^C is
pressed to abord aplay]
[The command is tried again, and it bails out as follows, w/o any sound]
	$ aplay /usr/share/sounds/pop.wav
	Playing WAVE '/usr/share/sounds/pop.wav' : Signed 16 bit Little Endian,
	Rate 44100 Hz, Mono
	ALSA lib pcm_hw.c:578:(snd_pcm_hw_drain) SNDRV_PCM_IOCTL_DRAIN failed:
	Input/output error
