I can confirm this problem is occurring on LM 18 Cinnamon 64-bit.

Kernel: 4.4.0-34
Audio: Realtek ALC233

I have try this patch, It was working once, until I closed hdajackretask, and after that, every try make sound completely disabled, like pulseaudio deamon not responding.

I was very happy to have my subwoofer, but it seem that this way is very unstable.
