[linux-audio-user] linux and alsaplayer

Hello list, I'm running gentoo kernel 2.20-gentoo-r8. I start jack (0.91.1) with jackd -vR -d alsa ,as root. muse is working (if started as root) so is ardour But when I try Alsaplayer -o jack somefile.someformat, it says "Failed to load output plugin "jack". Trying defaults." When I shut down jack alsaplayer starts playing perfectly Does it have something to do with the asoundrc-science? I tried copiing the jack-plugin text for .asoundrc somewhere from the alsa-site, the same result I thought it should work without the .asoundrc,but maybe I'm wrong. Anyone knows what I'm missing? Thanks in advance, Jaap van Geffen
