And no... im not going to install X either. No problem here. Just use "jack_lsp" to list the available ports and "jack_connect portX portY" to create connections between ports rsp. "jack_disconnect portX portY" to delete them again. All these are command line programs. I use X, but I don't like graphical jack patchers generally either. > If im going to use JACK to tie all this together, my first problem is getting > it > working with a multichannel ALSA device. > > The output card is a Envy24HT... i have asound.conf setup for a PCM per > stereo > output (evny_1, envy_2, etc). > > How do i tie these channels together to make a single 10 channel device that > JACK can then output to? You probably don't need to fiddle with asoundrc at all. Just starting jack as $ jackd -d alsa -d hw:0 should work. (Later you would do the the next steps, that include getting jackstart to work and using realtime mode.) It will simple use up all the in- and outchannels your card has to offer. "man jackd" will show you some more options to jackd, some of which will let you specify the number of channels to use or if do do playback only and such. ciao -- Frank Barknecht _ ___footils.org_
