 2007-06-11 10:19:20.441 AudioOutput Error: Access type not available:
 Invalid argument

 After some discussion on IRC in #pulseaudio :

 <mezcalero> the problem is here
  http://svn.mythtv.org/svn/trunk/mythtv/libs/libmyth/audiooutputalsa.cpp
  it assumes that SND_PCM_ACCESS_MMAP_INTERLEAVED is available
  that assumption is bogus
  only normal PCI hw has mmap
  it's the same issue why we have trouble to support quake with padsp
  people just assume that mmap is available everywhere
  they should stop doing that
 <mezcalero> atrus: you might want to file a bug and tell them that they
 need to fix their code
 <mezcalero> otherweise they will always have trouble with software
 backends
  or with a little bit more exotic audio hardware
  and i really wonder why they do that in the first place.
