I have just compiled and installed the latest version of ALSA. I have a Sony UX1XN micro-laptop and previously, whenever I have installed ALSA I have had no sound out of the speakers, but have had sound out of the headphones when I connect them. I have previously resolved this by un-muting the 'mono' track.
I open the volume control, select edit>prefs, select 'mono' and then unmute.
This time I have no 'mono' in the list. I get audio through headphones, but not through the onboard speaker.
How do I unmute 'mono' in the latest version of ALSA, or am I being really dumb?
Many thanks in advance.
