            Bug ID: 43725
           Summary: Unable to access MIDI ports from application running
                    inside wine
           Product: Wine
           Version: 2.15
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: winealsa.drv
          Assignee: wine-bugs at winehq.org

When running an application in wine that produces MIDI I'm unable to access
alsa MIDI port created by wine. I don't know why this is, but I noticed a
couple of strange things:
- The port is automatically connected to my soundcard
- I'm unable to disconnect wine's MIDI output port. When doing so using
"aconnect -d 129 16" I get the following error message "Disconnection failed
(Operation not permitted)"

Some relevant output:
$ aconnect -l
