Problem: The Panasonic Viera DLNA client always lists album tracks in alphabetical order when typically album track order is what is expected.
The Viera DLNA client does not request album tracks in track order, nor does the client have an option to do so. The workaround for this problem is to modify minidlna, specifically the file, upnpsoap.c. N.B. This change is not an attempt to fix a bug in minidlna, but a way to get around a limitation in a DLNA client.
