Are there alternative Linux programs you could try?
...and by-pass the use of ASIO completely?
Yes, and no .
Both Ardour and Audacity function well as far as basic audio recording,
but lack the ability to use the wide range of plugins available for Windoze,
both of these do have plugins available,
but Antares ( pitch correction,not to be confused with LADSPA pitch changers ),
Amplitube ( Cool guitar amp emulator )
And the list goes on ...
Audacity does not do MIDI
Ardour kind of does, but I have not had any luck mapping my controller knobs to it.
VSTi (instruments) do not work with either of these as far as I know.
The actual programs ( FL studio, Sony Acid, Amplitube, Antares, VST's, Etc. ) can be run and seem to work OK, I just cant get any functional external input due to the ASIO problems.
