Thanks very much. I got it working late last night with the OSS device, It now looks like
(after your response):
# general
-b:1024 -r:-1 -z:intbuf -z:db,100000 -n:alsa-96k -X -z:noxruns -z:nopsr
# audio inputs
-a:radio,mic -f:s32_le,2,96000 -i:alsa,ch12
# audio outputs
-a:radio,mic -f:s32_le,2,96000 -o:annotated_log.wav
# chain operators and controllers
-a:radio -erc:1.00,1.00 -enm:1.00,500.00,100.00,0.00,10.00 -gr
-a:mic -erc:2.00,1.00 -enm:1.00,1.00,0.00,0.00,100.00 -gr
I couldn't get 24/32 bit data out of the OSS device, but this gets me working with the
native alsa device again. BTW, if I use s24_le instead of s32_le, ecasound seems to record,
but will segfault when disconnecting.
I was a bit confused about needing to specify all 12 channels in the asoundrc, and only
specifying the channels I'm using in the ecasound parameters. I tried it, and it seems
to be working. I take back all them things I thought about anyone involved. (Though few
of them were directed at ecasound folks.) I now have something simple enough to run from
a PDA hooked up to a serial console - a little bit of solder and I'll be ready to get some
data. (Where would science be without burnt fingers anyway?) Thanks again.
Nate
