I think it is could be OS X which automatically limits its audio output
before it is sent to the built in dac. Makes my students write
computermusic that distorts on other computers than their latest
expensive apple laptop. Try on OS X with an external interface, it
should clip there as well or use a good VU meter to check levels
pre-dac. On Linux, there are good and precise meters in the x42-plugins package.

Well, do these apps output signals above 0dBFS (see "meters" above)?
