In Non-advanced mode plays fine:

bill:~$ aplay -Dhw:1,0 Hells_intro.wav
Playing WAVE 'Hells_intro.wav' : Signed 16 bit Little Endian, Rate 44100 
Hz, Stereo

In advanced mode:

bill:~$ aplay -Dhw:1,0 Hells_intro.wav
Playing WAVE 'Hells_intro.wav' : Signed 16 bit Little Endian, Rate 44100 
Hz, Stereo
aplay: set_params:900: Sample format non available

In advanced mode jackd says:
bill:~$ jackd -R -P70 -p128 -dalsa -dhw:1 -r48000 -p1024 -n3
jackd 0.103.0
