Question

Is it possible to have sound muted by default in ubuntu 17.10?

I have a cherry trail laptop with intel x5-z8350 processor. More info about my laptop, as you can see there are audio devices listed and recognized:

Solution

The above solution Will solve the problem sound but only headphones work.. Use the kernel 4.19 It supports the device well speakers will work Disable/ enable the sound card whenever you change the port Use alsamixer to look for left and right controls (HPO L...)
