Re: no sound on Lenovo Ideapad 110

Yes. It looks like sound card was detected and initialized, but Pulse
Audio was unable to set it as "default" automatically.
Have you tried to list and use available cards from alsa perspective
(your device names may be different)?
    $ aplay -l | grep ALC
        card 0: PCH [HDA Intel PCH], device 0: ALC887-VD Analog
[ALC887-VD Analog]
    $ aplay -L | grep CARD
    $ speaker-test -D front -t wav -c 2
If speaker-test works, but without actual sound from speakers, be sure
to check if sound channels unmuted:
    $ alsamixer
