Mplayer's volume control says it has changed the volume, but it doesn't seem to make a difference --- even when mplayer reports 0% there's still lots of volume. Probably the ALSA interface to bluetooth is not working very well. What alsa-lib and bluez versions are you using? And cat /proc/asound/devices shows only the on-board Intel sound card, not bluetooth. Thats because ALSA bluetooth support is via an alsa plugin provided by the bluez package, as all audio goes via the bluez stack.

There is a GNOME bluetooth applet that allows you to pair devices, send files, etc. Probably something for KDE as well, but I don't know what its called.

Setting up without all that stuff is really painful. Bluez relies heavily on dbus, which although it has shell and python tools for manipulation, they are verbose and hard to type.
