(lspci -v) here are some questions: -what's jack's output, if you run it as su with the realtime flag? -if you use an input signal and any program, that accesses the sound device, can you try to check some hdspmixer settings? on my system a part of the audio data that's send to the computer is sent to the corresponding output instead... > However, once I switch over to the hdsp in the modules.conf file, > everything runs but extremely slow...

(Very > beautiful in a twisted sort of way!) i experienced this with aplay ... i recorded it with another computer and it seems that 32 samples of the soundfile are followed by 32 samples of silence ... does the _pitch_ of the distortion change, if you change the samplerate with hdspconf? > My machine has is 2.8 Pentium 4, plenty of horsepower, and two pcmcia > slots (only one works with hdsploader for some reason). wait ... i can only use one cardbus slot, too ... can you check the irqs of your slots? (mine are 5 and 11) we still don't know exactly, where this problem comes from ... thomas charbonnel (maintainer of the alsa driver) suggested that it's probably a cardbus driver problem (is it working with windows on your machine?) ... iirc you are the third person, having these kinds of problems: my laptop is a p4 2.5, with an o2micro 6933 cardbus bridge ico's laptop uses an amd64 and an ENE cardbus bridge ... both are chipsets that might cause problems with the hdsp, but on both ico's and my machine, the hdsp works fine with windows xp... i hope we will be able to solve this problem, soon, i'd suggest to move this discussion to the alsa devel list, since it's probably not a problem of the configuration, but of the hardware... btw, is it possible for you to come to the lad conference in karlsruhe, next month? since ico, me and probably thomas will meet there, and hopefully can track down the problem, it would be easier, to have 3 machines with this problems there than only two... cheers ... and i hope you have more luck than i had...
