Doesn't module-combine-sink work?

The playback speed is determined by the hardware, not by the
application.  When an application tries to write more data than is
currently possible, ALSA will just wait.

This does not work if the playback is coming in real time from a source
whose speed you cannot control, such as an S/PDIF input or broadcasting
TV.  In that case, you eventually get the same problem.
