The audiomixer element can do that. You have to configure a latency (see
property of the same name, in nanosecond). This latency will allow a bit of
delay between streams. If a stream goes missing, the timeout will be
reached, and only available streams will be mixed. If they are all gone,
silent buffers will be produced. If you have a mean to detect idle stream,
be aware that performance is slightly improved if you remove the requested
pad, as it may no longer have to wait for the timeout to mix.

Thanx.
