Most speakers don't work

[JonathanReeve]

I have a Lenovo Yoga C-930, which has a Dolby sound bar, and it seems that only one or two out of six speakers work. Is there a way I can make this work?

Ask Lenovo to add the initialization for all speakers to the BIOS.

Is there another way that we could initialize those amplifiers? I've been in contact with Lenovo several times, and they just turn off completely whenever Linux is mentioned.
