So I'm afraid, for the moment, this will not work. The reason for the oops is that the code does not check (having found a translation table) that individual routines are *all* present. This will be fixed at the next patch release. I may do a read translation (but... feel free ;-) Note that these days kernel-based sample-rate & size conversion is deprecated. It really requires FP to do the job properly. Much better to record from /dev/dsp in some appropriate 16 bit format and then convert off-line using sox or something like that.
