I did as Paul suggested in qjackctl and set the frames/period to 2048. Same error. At 512 frames per period and below qjackctl seems to run fine. Above 512 I get the same errors that jack server cannot start. Still no evidence of anything hitting the soundcanvas. Qjackclt gave me the options of hw:0, default, and hw:1. The latter gave me the heinous error message popup, former 2 did not. BTW - alsaconf is not at all installed, nor appears available. My synaptic package manager informs me that I do indeed have alsa-utils, looking at the properties/dependancies the file alsaconf falls under the category of : Conflicts: alsaconf Conflicts: alsaconf-0.4 ... Replaces: alsautils Replaces:alsaconf for what it's worth. thanks, Phil J. > > >>Debian/Apps/System/Admin/Alsaconf >>but it wants me to log in as root (not as sudo su) and I >>don't recall the password I set...arrg! >> >> > >...and enter the root passphrase, then type /sbin/alsaconf. > >OTOH, Paul Davis threw in that it's not an ALSA problem but a >JACK one.
