As I said in my previous query I have recently aquired a new computer, a Nofan A470 from QuietPC.com with on-board audio Realtek ALC650 6 channel, and I have installed Debian Testing/Jessie from scratch.
I have done a lot of internet searching regarding these problems but have not found anything which works.

I'm using Fluxbox as my desktop although I have some KDE applications installed. The audio seems to work without problems with any KDE applications but not with anything else.
For example - I use mail-notification which shows as an icon in the bottom toolbar and I can set it to play a sound when new mail arrives. That can be set in the configuration, an it is, and which also allows a test play but there is no sound. I believe that mail-notification is Gnome based.
I have also installed Timidity plus the standard patch files but can't get any sound although it appears to be playing.
There are some Phonon and Alsa packages installed.

Also with mail-notification I should be able to click the icon and get it to open Balse, my mail reader, but clicking does nothing. When mail- notification was installed it started Evolution when the icon was clicked but I didn't want Evolution and uninstalled it. I can't find any way to set mail-notification to open Balsa.

The last thing is that I use Krusader as a file manager and I want text files, by default, to be opened using Mousepad. At present the default is Libre Office and I haven't been able to change that. In the Krusader configuration there is an option to set which editor to use and I have set it to /usr/bin/mousepad but that appears to be ignored.
Any pointers would be gratefully received.
