Inge - waves of empathy.... i had a very similar set of problems...finally found out about the realtime-lsm, but simply could not get the damned thing to compile,(see my mail of yesterday - maybe someone will still be able to help) so you were a step ahead of me...
i am now trying with a demudi install....an improvement for me, but it still is not doing all it should. What with that and a grizzly bug in audacity that means i can't edit with that either, i also contemplate throwing in the towel after a decade of *nix use... It really is still a bit of an uphill battle. Hopefully Agnula will produce something worthwhile, most importantly because they seem to be intent on producing documentation. good :) The problem at the moment seems to be that the different distros, and the 2.4/2.6 and all the 2.6's all are sufficiently different on the alsa/&c things to make any partial clues culled from google not always very useful. Do let us know if you have a breakthrough/insights. dee On Sun, 15 Aug 2004, Inge Thorin Eidsaether wrote: > > Hi > > I'm having a few problems getting jackd to work > on my Debian box (testing, kernel 2.6.7) > The soundcard is a Soundblaster Live. > > Sequencial summary (so far): > > ALSA seems to be working, that is: playback works. > Haven't tried recording yet.
