Thanks, will try this, but mnay questions remain (see below).

Aha, that is good news.

Will things work with the current Arch packages and do I
need git just becuase it has the minimal.conf file ?
If yes I'd prefer to use the Arch packages for now.

Questions:

* A lot of lines in the minimal.conf are commented. Can one
  assume that these correspond to the defaults ? If not, what
  are the defaults for all these parameters ? 

  What concerns me here is things like 

            #channelmix.normalize  = true
  
  I certainly do not want any normalisation, so do I need
  to set this to false explicitly ?


* The sample rate (48000) is in many places, most of them
  commented out. What is the relation between all of these ?
  Why, for example, is 'default.clock.rate' commented ?

* 'quantum', 'period-size' and 'period-num' are commented
  out everywhere (except in 'vm.override'). So where is
  the period size defined ?

* If things like sample rate, period size, etc. are set
  to some fixed values in the config, can they still be
  modified by e.g. pw-metadata ? I hope not...
