[Sound-open-firmware] Handling SIGTSTP (Ctrl+Z) /SIGCONT/fg with aplay/cplay

Hi all,

Is there any quick document for handling Ctrl + Z with aplay/cplay?

I don't see this signal handled with alsa-lib or tinycompress although linux kernel offers PAUSE/RESUME ioctls.

What should be the expected behavior?

thanks, Daniel.
