Hi, I think the problems you described are fairly common with the Multiface. I have never gotten PD to work with a Multiface. XMMS does not work well, either, nor does mplayer (oss emulation is really no good, and it mplayer will not play through alsa with this card). Alsaplayer will work pretty well (better through Jack on my system), but I had to disable cddb-lookup because it would stall with CD's it didn't recognize. Xine will not work, and with the particular incarnation of kernel/drivers I'm using (ccrma), Audacity has been slowed to a complete crawl (it takes between 1 and 2 minutes to start up, and 1-2 minutes after you enter a command to execute it) - hopefully this will change when I upgrade. I suspect a lot of this is because the drivers are relatively new. I think Thomas Charbonnel (sp?) wrote the HDSP drivers (kudos), so he may welcome bug reports. Matt PS, which flavor of linux are you running? ->Question two: I get this error with pd and the multiface using non-interleaved audio input Sample width set to 4 bytes snd_pcm_hw_params_set_access (output): Invalid argument using non-interleaved audio pd: pcm.c:1133: snd_pcm_readi: Assertion `pcm->access == SND_PCM_ACCESS_RW_INTERLEAVED\\\' failed. Pd: signal 6 and xmms sees the card (proabably from my .asoundrc file) but wont play through it. Ive run hdsploader and the little red host error light is gone, so whats up?<-
