Гигабайт P34Wv4-BW1T Ubuntu 15.10 не аудио from speakers

гm trying to get Ubuntu working on my new laptop. гm having в few problems and гm very frustrated. The first problem (I will ask different questions for the others): гm not able to hear sound from my speakers. I am able to hear sound through my headphone jack, though.

lspci-v | grep-A7-i "аудио"

my@my-P34V4:~$ ^C

my@my-P34V4:~$ lspci -v | grep -A7 -i "audio"

I went into the alsamixer and unmuted what I could. That didn't seem to help.
