[LAU] ecasound/jack records empty files

Hi all, I'm trying to build a recorder that makes a 24 hour long audio recording, with multiple channels. So far, I can start jackd: $sudo jackd -d firewire and start ecasound: $sudo ecasound -a:1,2,3,4,5,6,7,8 -f:s16_le,8,44100 -i jack,system -a:1 -o channelone.mp3 -a:2 -o channeltwo.mp3 -a:3 -o channelthree.mp3 -a:4 -o channelfour.mp3 -a:5 -o channelfive.mp3 -a:6 -o channelsix.mp3 -a:7 -o channelseven.mp3 -a:8 -o channeleight.mp3 ...this starts recording without problems. However, when I stop recording by issuing ctrl-c to ecasound and then start recording again, the files created now have zero bytes. If I stop and restart the jack server, then recording works normally. I would expect ecasound to overwrite the files and record new files; why must I restart jackd for audio to be recorded? Thanks for any info. -Steiny (415)819-2009
