I am trying to run JACK using the PulseAudio plugin for ALSA. When I try to start JACK, I get an error saying that mmap-based access is not possible for the audio interface. Is it correct that there is no mmap support in the PulseAudio ALSA plugin? If so, does anyone know of a way around this to get JACK running with ALSA & PulseAudio? Thanks, Andy FYI, I am running Ubuntu feisty with: libasound2-plugins v1.0.13 (this includes the PulseAudio plugin for ALSA; I presume it is v0.9.5) jackd v0.102.20 "aplay -Dpulse foo.wav" works "jackd -d alsa -d default" works, where the default card is the dummy output (/dev/null)
