Comment 18 for bug 1551385

I just completed a fresh install of Ubuntu 16.04 with a brand new Asus Xonar DGX. I can confirm the bug exists and also that the alsamixer workaround is sticky across reboots. While the current workaround is much better than nothing, I' d like a way to have sound on both speakers and headphones at once, the alsamixer solution appears to offer a one-or-the-other switch but not both. Anyone figure out a solution for this?
