Okay, so this has been bugging me for a while now, but I'm not sure how to fix it, or to troubleshoot it further. Maybe somebody here can help.
There are two issues, and they may or may not be related. I'm currently on F29, but it happened before I upgraded, too.
1. In gdm, the volume indicator always indicates the output device is Headphones, even when headphones aren't plugged in. gdm doesn't make a lot of noise to debug before logging in, so I'm not sure if it's trying to play through the wrong device, or if it's a UI problem.
2. When I log in (I'm using Wayland), everything works fine for about 10 seconds. After that, the volume is automatically muted and I have to manually unmute it again (even if I've previously muted and unmuted it before it reaches 10 seconds).
I've tried every knob I can find in the gnome settings, pavucontrol, and even reset the entire ~/.config/pulse directory and rebooted. Nothing works.
I have no idea what's going on. Can anybody suggest a fix or help me identify the problem?
