No sound on ubuntu 18.04 on lenovo ideapad 100s (11iby)
I've just installed ubuntu 18.04 on a lenovo ideapad 100s (11iby). Everything works apart from the sound.
I'm a bit of a linux n00b, but I have 20 years experience as a software developer on windows, and have dabbled a bit with linux - including managing some linux-based firewall/VoIP boxes, and the command line doesn't scare me in the slightest. Obviously all of that is completely useless for this, but just trying to say I understand computers well, just not really the *nix world well... :)
I've tried to follow some of the steps here:

The weird thing is, *some* of these steps appeared to work - that is, sound suddenly started working. Now I'm fairly sure that all I did was diagnostic stuff at first, so didn't really change anything. However, when I rebooted it went away again. I tried re-doing what I thought I'd done, but then it didn't help... further messing about with other steps then yielded the same result - suddenly came to life, but a reboot once again killed it.
The symptoms are simple: no sound, and absolutely no devices listed under Sound in settings. When it works, I have 5 devices listed here
this morning now, whilst writing this, it appears to have spontaneously come back to life again. All I've run today is the wget command to fetch the ALSA info, I don't believe I've tried to change anything. Could it be I just have to wait 5-10 minutes after boot or something? I'll reboot after I've posted this and post whether it's working.
The troubleshooting page doesn't appear to mention 18.04 much. That said, it did suggest in step 3 running a command to dump out a load of ALSA information and post a question here, so that is what I'm now doing. it says to copy the output report to this post, but the ALSA tool appears to now suggest uploading it for you and gives a link, so I'm adding that here - I assume this is ok?

Any ideas? As I said above I'll reboot in a moment and wait half an hour or something and see what happens...
Thanks
