I have set up various smartlists with a random sort which works great on the PC interface.
Each time I click the playlist I get a different file selection. While using the UPnP server however I can select a random smartlist, start playing, select another playlist and start playing it, when I return to the first playlist, the list of songs is the same as before.

I checked to see if it was my receiver that was caching the playlist, but in the Sniffer (Ethereal) trace I see that MC 12.139 is returning the same file list from the UPnP server. Is the caching of this response the expected behaviour?

I have Smartlists like: -

20 Male Vocal Songs
20 Female Vocal Songs

and would like it to be a new random selection each time it is requested. (Like the PC interface)

Any ideas? Could find nothing in the forums searching for smartlists and UPnP

Hmmm... this may be broken, but it may be working as expected.

For technical reasons, the UPnP server has to be careful about redoing the random order of a smartlist.
It keeps track of how far away from the smartlist you browse in your library. If you get far enough
away, it should re-do the randomness of the smartlist.

I'll take a look tomorrow to make sure everything is working, but for now, try going up two levels before
going back to the smartlist.

Here's a longer explanation:

It looks like it's working correctly. Let me know if you have any suggestions or inconsistencies...

Thanks John as always.

Yes after further experimentation (after reading the Wiki) it does provide a new selection if I go back another level in the menu.
You mention that changing the playlist to dynamically may cause problems, i guess that is because some devices are not designed to handle such events. Thanks for checking and the expected behavior based on the explanation makes sense.
