I have a Lenovo Yoga Pro 2 and have been having problems with the sound from the internal laptop speakers. I think I initially had this problem when I installed 18.1, and don't remember how it was fixed. A couple of months ago I did an update and it broke. I ended up upgrading to 18.2 and it still didn't work. I've tried messing with alsamixer and PulseAudio Volume Control with no luck. At some point it seemed to have randomly fixed itself (only the left speaker) and a few weeks later just stopped working for no reason I could figure out. The sound currently works through my headphones and through my bluetooth speaker. I really want to fix this as the sound from my bluetooth speaker is really crackly and not that much fun to listen through. You can consider me a newbie but I can follow instructions and have used the terminal before. I wondered if perhaps the right device is not being recognised. I really hope someone can help, Thanks!
