In the pd documentation, on page x3.htm#s4, it list under the LINUX only commands -stream as being a command line argument to envoke an es1370 audio card. See below.
(linux specific audio:)
-frags -- specify number of audio fragments (defeats audiobuf)
-fragsize -- specify log of fragment size ('blocksize' is better...)
-stream -- use stream mode audio (e.g., for es1370 audio cards)
-alsa -- use ALSA audio drivers-alsadev
-- ALSA device # (counting from 1) or name: default hw:0,0
