Upgraded to 6.1.1 and now see tracks being sent multiple times to Last FM:

Is this just me? I saw this on an earlier version and problem went away and now seems back. Want to verify if others are seeing this. Thanks.

When I play a song from the web interface there are no duplicates, however I see duplicates when playing from iPhone app "iSub"

So using a browser to play music I only see one entry scrobbed to Last fm. If I use the Sonos controller to play the song I see the duplicate entries. So if someone on 6.1.1 has Sonos setup and could confirm I would appreciate it. Thanks.
