Yes, it's a problem with Pd's ALSA code. What's even worse than the
latency issue, which I could live with, is that it isn't possible to
select ALSA pcms by name. You're stuck with hw:0, plughw:0, hw:1,
plughw:1, and so on. This basically makes it impossible to use Pd with
asoundrc tweaks and thus with some more advanced multichannel setups
in ALSA mode. These are known problems. I lack the ALSA knowledge
to do anything about it and those who have the knowledge lack the
time, but it would be great if those issues could be sorted out some
time. I'm sure, they will, though.

ciao
