Hi Philippe

Here is what I tried:

sudo rm -R /usr/lib/python2.7/sites-package/ffado
cd $HOME/bin/ffado-svn/libffado (this is the directory where I build ffado
rm -R cache
rm .sconsign.dblite
svn checkout http://subversion.ffado.org/ffado/trunk $HOME/bin/ffado-svn
scons ENABLE_OPTIMIZATIONS=True PREFIX=/usr ENABLE_METRIC_HALO=True 
DEBUG=yes
sudo scons ENABLE_OPTIMIZATIONS=True PREFIX=/usr ENABLE_METRIC_HALO=True 
DEBUG=yes install

But now many things seem broken, ffado-test Discover gives:

01161040498: Warning (Configuration.cpp)[  67] openFile: Could not parse

However ffado-test ListDevices correctly list the devices:
=== 1394 PORT 0 ===
   Node id  GUID                  VendorId     ModelId   Vendor - Model
    0       0x00130e0401c00f89  0x0000130E  0x00000007   Focusrite - 
SAFFIRE_PRO_24
    1       0x0017fb340000e0f4  0x000017FB  0x00000000   Linux Firewire -

What is the first warning? /usr/share/libffado/configuration is present 
and seems correct. Have I broken something by my reinstallation?

jackd fails with the same message about doFcpTransaction.

ffado-mixer says "No supproted device found".
