They don't specifically have to know about suspend and resume - from the
application point of view it just looks like an underrun - poll() or
write() will return an error code so the app checks the state with
snd_pcm_state() and recovers if it is SND_PCM_STATE_XRUN or
SND_PCM_STATE_SUSPENDED.

Are any of these native ALSA apps, or do they all go through artsd which
uses the OSS emulation layer?

Does it work OK with aplay?
