In this machine I have, by chance, also got gnome classic login session available. I notice that in sound settings, using gnome classic desktop environment, the mode using 'Analogue stereo Output', works ok. However, in Unity, only 'Analogue stereo duplex' (not 'Analogue stereo Output') is offered and this does not work, (and in other earlier versions of Ubuntu over the years, has never worked in these three different machines). It seems to me to be significant that the particular setting is not offered, or is not recognised. I attach a couple of screenshots of sound settings, one of unity, the other in the gnome classic desktop in this machine.
