Roman you're right, a -noaudio Pd doesn't sync with a device and
therefore it can not have sync problems. Thanks for pointing to this.
It did not cross my mind to do signal tests with -noaudio but it may
be a good idea, to exclude sync troubles in any case. Pd started with
-noaudio is the same as Pd with input- and output- devices disabled,
and this can also be done with an audio-dialog message.
