I can confirm those steps. Only when I display the devices there's the conexant speakers marked default and an extra device sdif-interface conexant audio and when right clicking on the conexant ( just like on the shown example ) it list : configure speakers, test, disable ( so not enable !!!) device, show all disabled devices, show all disconnected devices, about software midi synth, properties.
So according to this it acts like the speakers are enabled but still on the taskbar there's a red cross next to the spakers and a left click and then troubleshoot results in not connected device !!
Thnx for letting me pick your brain.
