I have three applications that want to use the sound card, two audio stream players, and
a voip phone.
I want to set up linux so that if a call comes in on the phone the OS
will disconnect the audio players, give exclusive access to the voip
phone, and then when the phone is done reconnect the audio players to
the sound card.
How can this be done?

Regarding to the German Wiki PulseAudio should be able to handle stuff
like this. While PulseAudio is a PITA to many Linux audio production
users, IIUC PulseAudio should help for needs as yours. Of course you
have to code apps, resp. to use apps that were programmed for usage with
PulseAudio.
I've got no knowledge about this!!, but if PulseAudio shouldn't be able
to handle this kind of things, than I wonder what the advantages of it
should be.
Unfortunately the Wiki on English isn't that informative as the German
Wiki ... I anyway didn't read the complete German Wiki.

Thanks for your feedback. The system my application is going to run on
will not include PulseAudio, so I would have to do it with just ALSA and
the OS.

ALSA contains the building blocks needed to implement such a system
(this is how PulseAudio can do it) but it does not offer this
functionality in a form for users to use. Put differently, you could
write code that would do what you describe, but there is nothing on
your system as-is that will do what you described.
