Hi, I have a Creative Zen 4gb music player (which uses MTP) that I've been able to use fine since the Hardy beta, but after a fresh install of Ubuntu, I've been having a problems with it. I use Gnomad2 and Rhythmbox to transfer files to the player, but as of recently, when I plug in the player and load either Gnomad2 or Rhythmbox, the player freezes to a black screen and I have to do a hard-restart to get it to turn on again. I've never had this problem before and have no idea what's causing it.

I have all the gstreamer codecs installed, and all my system sound preferences set to OSS.

I did notice that neither ALSA or Pulse Audio seem to be working for me in the system sound preferences options... Maybe there's a problem there that is interfering with my MTP music player functioning properly?
