Hi Hazel,
I think you need CONFIG_SND_HDA_INTEL (the module is snd-hda-intel,
which you seem to have loaded), and probably you will need to enable
most of the codecs listed below it in menuconfig.
Unfortunately, for those of us who use analogue sound and alsa, this
driver is a bit of a pain on some machines. On my two most recent
desktop machines, and one previously, alsa gives error messages, e.g.
when trying to use alsamixer. For those I have to use ~/.asoundrc -
my current version is attached. Interestingly, one of those two
machines is an AMD A10 Kaveri which replaced a previous one where
the mobo died - much was similar, but the previous one had working
sound without the ~/.asoundrc.
Also, if you need that ~/.asoundrc then analogue sound is probably
quiet - maybe not a problem for you, but it is for me, I have to
turn the amplifier up to 11 - at least I use headphones, so it's
only me, and not my neighbours, who gets hurt if I leave the amp
turned up and use a differnet machine ;-)
Surprisingly, building Pulse Audio for firefox-52 has rectified
the volume, at least for youtube.
