This is less efficient than it could be. Consider using a hardware device instead rather than using the plug layer. Usually the name of the hardware device that corresponds to the first soun ALSA lib pcm_mmap.c:368:(snd_pcm_mmap) mmap failed: Invalid argument ALSA: cannot set hardware parameters for capture ALSA: cannot configure capture channel cannot load driver module alsa ;;; The iMic, including recording, works with other programs, i.e. esd (if called as plughw:1) and with programs using the oss-emulation in alsa. Jackd is working fine on the other soundcard, but I want it on the imic (so I can record). Thanks in advance, Sunnan
