hi all,

i'm still working on my problem with the maudio quattro:

oss-mode:
using /dev/dsp1 and a symlink from /dev/adsp1 to /dev/dsp2, i can't
access both input devices, but when i create a dac~ object, i get an
additional sound at about 690Hz. (pd's output level is at 97dB).
using only one of these two devices works fine...

alsa-mode:
using both hardware and plugin mode i don't have the possibility to
access all channels, only the channel hw:1,0, not hw:1,1. using
-channels 4 only maps the channels 3 and 4 as 1 and 2 (hardware) or only
gives 2 channels.
the playback sounds odd, too, it seems that the blocks doesn't reach the
alsa driver in time ... 

portaudio:
i failed compiling the portaudio support. it seems that pablio is
depending on a PortAudioStream, that i only implemented in the mac
version of portaudio, yet... 

i haven't got jack working yet ... if someone could tell me how to run
jack from the command line with 4 channels, i'd be glad ...

but i'd prefer to figure out how to get the oss layer or portaudio
working properly...

thanks for your time and help...
