Unfortunately the problem is still there :/

Maybe a quick and dirty solution would be to simply not create the watchdog
thread when it is not needed (e.g. for the various --version, --help and
similar options). Not sure how much work would be needed (or if it will
actually resolve the issue) though.

Just running "ecasound --version" (or "--help") works as well. What I do is
simply running the command several times until it gets stuck.
