With latest radio version, frequently, sound volume goes to zero!

[user-removed]

[I posted this on the Spotify Community Wish List Thread, but maybe it's better here.]

Ever since I added the latest version, frequently, Spotify cuts the audio volume to zero. The track is shown as playing, but no sound!

I've tested it all sorts of ways and conclude it's Spotify whether on WiFi, cell signal, "radio" or playing downloaded songs.

I can (sometimes) work-around, by hitting "pause" then "play." But who needs it?!

Anyone else experience this? Know of a solution?

I'm running what I call the Radio Version, shown as 0.5.3.56 (0.8.3.665 ga9b08536) on my AT&T Samsung Galaxy SII, (not a small market phone!)

Thanks in advance.
