[solved]mythmusic: doesn't play from automounted extHD

[schitthoch3]

HI all

My music collection is plugged to my combined backend/frontend box on an external usb-HD, which has a seperate power switch.

Normally i use this box for recording/watching TV, so i leave the extHD turned off. in my fstab i have therefore the argument "noauto" for /dev/sda1 (which is my extHD music partition).

A year before i had configured ivman under KDE to automount the ext-HD when i power it on to listen music via mythmusic.

ivman reads the fstab entry and then mounts the extHD accordingly as soon as it is powered on. Later i switched to IceWM and it still worked like a charm. but when i tried to listen some music 5 weeks ago, mythmusic did not play the files (no error message).
it just does not play a file and playtime does not show up too, while cover,ID3 aso are showed correctly. mythbackend.log neither has an error messages. syslog on the other hand does log every second the following message (only when mythmusic tries to play):

Have you tried re-scanning your music folder once the drive is mounted? Lots of the meta-data is held in the mysql database, which might be why you're still seeing part of your data.

yes, i re-scanned it before posting, and now just another time. but it still doesn't play.
interesting: mythmusic on a FE-only-client, which mounts the to the server connected extHD via autofs DOES play.

OK, here we go.
