This is definitely my fault. I haven't hardcoded the ID of the RME
formats in the soundcard.h file of the kernel, now the same are taken away
by AC3 or so. ... The solutions are to change the
AFMT_S32_BLOCKED define at the start of s_linux, I have to do
so in my driver too, or to make pd runnable with the RME ALSA
driver, of even better with jack.
