           Summary: kmix locks alsa modems snd-intel8x0m
           Product: kmix
           Version: 2.6
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: esken kde org
        ReportedBy: leon bottou org


Version:           2.6 (using KDE KDE 3.5.2)
Installed from:    Ubuntu Packages
OS:                Linux

Kmix prevents my laptop to suspend and resume properly.

Explanation: 
My laptop uses an AC97 modem via the ALSA "snd-intel8x0m" linux module.
By default kmix controls all ALSA devices including the modem.
Alas the suspend code needs to stop the modem daemon and remove 
the modem module. That does not work because the module is in use.
Kmix keeps /dev/snd/controlC1 open.

Workaround:
Inserting 'killall kmix' in the suspend script.

Question1:
Do we really need to see modems outputs in kmix?
In principle, this allows us to to change 
the volume of the modem feedback.
Alas it rarely works.

Question2:
Even if kmix needs to control the modem outputs,
is it necessary to keep the device files open all the time.
It might be possible to close them after a few seconds
of inactivity.
