[pulseaudio-tickets] [Bug 107037] module-udev-detect fails to create sink for sound card

--- Comment #9 from Alex Henry <tukkek at gmail.com> ---
This issue is resolved now and too minor to trigger a reworking of the log
system. My suggestions would be:

1. Do change the log message from a warning to an error regardless. Not
being able to access the sound card is an error and an unexpected situation
which will lead to other problems (as seen in the original complaint).

2. Your --started-by solution seems to be desirable on its own. I would
suggest opening up a new bug report so that knowledgeable people can
discuss the best solution to the current logging situation and then proceed
to implement it.

Hopefully the combination of the two might result in better logging to this
particular problem but I think #2 is out of the scope for this particular
issue and should be discussed on its own merits.
