Unfortunately, not all of my messages to the lists are being delivered on time. I'm getting "Mail Delivery Status Notification (Delay)" with this kind of error:

 [Status: Error, Address: <bug-guix@gnu.org>, ResponseCode 421, Host not reachable.] 

In a previous message that Florian responded to (https://lists.gnu.org/archive/html/help-guix/2019-05/msg00116.html), I added a bit more information about the problem. I also reported a bug that has been delayed as well.

In summary, most of the time, when I start the machine (a real machine), "GNOME Setting → Sound" shows a "Dummy output" as the output device, not the real device. Only once, I started the machine and sound worked fine, both in desktop applications and in the IceCat browser. GNOME even displayed information when I plugged some headphones and "GNOME Setting → Sound" displayed the real device and headphones as output devices (no "Dummy output" any more). That time, I started the machine with the headphones unplugged. So I thought that could be related to the problem, but then I tried to reproduce it and couldn't. And I lost sound again.
