I’m using RPI with Volumio 1.4 in my car as a stanalone audio player.
It is set up as a wi fi hotspot and I control it from my symbian smartphone using qmobilempd.
The power supply is pretty straight forward and there is no any shutdown process for RPI when I turn the power off.
So, the problem is that playlist status changed with MPD client is not saved after power shutdown and next startup. I can even create a new playlist and start it’s playback but after RPI restart it plays with old playlist.
Sometimes “update mpd database” command issued from mpd client helps but not always. I suspect this is a problem of the write buffer for SD card so when I suddenly power off the RPI, the buffer is not flushed to the SD card.
I may be mistaken though.
Is there any workaround for this? (I don’t really want to do a power shutdown controller). some sort of regular buffer flushing ?
