Error "could not export dbus interface", and alsa.so

[ThomasP]

Hello,

when I run the latest baresip version, I get two issues/errors:

1. There is no alsa.so in the build/modules/ directory

2. A msg saying 

...

ctrl_dbus: bus aquired name=com.github.Baresip
ctrl_dbus: dbus name lost com.github.Baresip
ctrl_dbus: could not export dbus interface

...

is displayed upon startup of baresip. (The last of these lines in red, so an error apparently.)

I am using the latest baresip repo code, v3.4.0   Compiling worked without notable issues. 

An older version of baresip, v1.0.0 from a debian package, worked well (but lacks some newer features).

Is there any hint as to what the cause of above errors could be?

Thnk
