Motherboard: Gigabyte GA-Z170X-Gaming GT (rev. 1.0)
Description: Ubuntu 19.04
Release: 19.04
Expected behavior: Audio playback via headphones
Actual behavior: No audio playback heard
If I start Ubuntu 19.04 directly after booting my PC, there is no sound from the front or rear outputs. Everything seems configured correctly in Alsamixer, etc.
If I boot into Windows 10, then restart and enter Ubuntu, the sound works as expected.
I suspect something is being set properly by the Windows driver that is missed in the native Linux driver. The fact that it survives a (soft) reboot is interesting.
I know this is at the ALSA level or below, because if I stop pulseaudio, `aplay music.wav` produces no output before starting Windows, and works after starting Windows.
