You do not need to fix it, I would consider it a major improvement and
call you a sage, if you could only tell me, what could be the actual
reason for it. I suspect, that I could find a way to fix it myself and
share this fix with the world if I only would know wehre exactly to
begin I was even grepping thru /etc in the faint hope to find that
config-file that has something related to that message.

It is a part of PA, so much I did find out:;a=blob;f=reserve.txt

so it is PA in collaboration with dbus. Do you know a place, where I can
find the documentation how dbus is configured to run PA in Ubuntu?

You know and I know, that this has nothing to do with my hardware. I run
this gear all day perfectly OK once I have started it by un/replugging
the interface several times. And I can reproduce the problem at will. It
is  a matter of software, software-setup I guess.

Ohhh sorry for that I thought delivering a working system was your
promise anyway, I only asked for a promise to not forget that.

Last time I checked, reporting bugs was considered something to move a
project forward. So I expose to you my bug, you crush it, get the fun
and the fame.

To increase the motivation I am willing to work for you by providing a
solution for you latest project: running Ubuntu Studio in another DE. So
you got the time to find a coder who actually *knows* what part of Pulse
audio is causing that registration of my USB-soundcard.

I am working on this for about a year now, for me and for others, that
have the same problem. Most of them do not even try to fix it, they
simply reboot....

excuse the venom please... its late....

best regards
