Problem: Pressing Control-c while playing certain sound files under
Linux 2.2.x does not have an effect until I press Control-z
shortly after.

Example: "cat something.wav > /dev/dsp" cannot be stopped by Control-c
but if I press Control-z shortly after, it does stop (and not
suspend). This also happens with playmidi and .mid files,
but *not* when cat'ing .au files.

I've seen this problem on several 2.2 kernels including 2.2.9, on at
least 2 different machines with at least 3 different sound cards.
This problem does not occur with 2.0.36 -- Control-c stops the sound
immediately.

Any idea on what may be going on here? Is it just me?

Thanks,
Navin.
