Hi,

Sorry to be late but I caught a cold last weekend and some works were
postpone.

I can reproduce this bug. A workaround is to run ffado-dbus-server in
advance, then launch ffado-mixer. I don't know the cause of this bug
because it's long ago I worked for ffado tools.

I think the message is like:
Error (avc_avdevice.cpp)[ 300] supportsSamplingFrequency: sample rate
not supported by input plug

I don't know the cause.

I think it's a bug of Qt4 tools on recent desktop environment based on
Gtk. I can reproduce it with qsynth and kmidimon. I don't know the cause...

The ffado-mixer utilizes ffado-dbus-server to communicate to actual
devices. But the program is not better shape as a system server or IEEE
1394 application. You must stop a process of the server when you close
ffado-mixer or you re-connect your model to system.


Thanks
