I compiled the aloop module and it works fine, but when I try setting up
the asoundrc as described, and use the device, I get.
ALSA lib pcm_dmix.c:1018:(snd_pcm_dmix_open) unable to open slave
aplay: main:654: audio open error: Invalid argument
Does anyone know what this uninformative error mean? Has anybody ever
had luck with a similar setup?

Hi, I use this setup as described in the wiki page (I wrote that page myself ;) and have
no issue.
You should provide the version numbers of libasound and alsa, how they were installed,
etc.
Version mismatch can cause this kind of problems I think.
Well, libasound is a
Debian package from Squeeze and is 1.0.13. The
drivers are from kernel 2.6.33.7.2-rt30, apart from aloop which is from
release 1.0.24 of alsa-drivers. Aloop compiles and loads fine and seems to
work when used standalone, but once the asoundrc is in place, I get the
error described earlier.
Cheers,
