When I play video or audio in the browser or in the desktop, I get no audio= . The volume controls in the browser and desktop show the sound is not disa= bled. There are no errors about missing codecs or anything like that. The m= edia=20 plays, but there is no audio coming out from the speakers (which are on). A= udio and speakers worked fine in the distro I was using before installing G= NU with Guix. I posted this issue to help-guix (https://lists.gnu.org/archi= ve/html/help-guix/2019-05/msg00107.html). This is what I've tried so far: When I go to GNOME Settings =E2=86=92 Sound, I get this: https://multimedialib.files.wordpress.com/2019/05/dummy-output-gnu-guix-1.0= .png The name of the only device listed there corresponds to "Dummy output" in E= nglish. So, for some reason, the system is not detecting the real sound dev= ice. Running: guix environment --ad-hoc alsa-utils alsamixer displays this:=20 https://multimedialib.files.wordpress.com/2019/05/alsamixer-guix-system-1.0= .png When I press F6 in alsamixer I see "(default)" selected, and there are no o= ther options, except for an "enter device name..." option. I get this behavior almost every time I start the machine. Only once, I sta= rted the machine and the speakers worked. The real sound device was display= ed in "GNOME Settings =E2=86=92 Sound", and GNOME would display information= when I plugged some headphones. However, I don't know why it worked that time. I thought it had worked beca= use that day I didn't plugged the headphones before booting, but trying to = reproduce the behavior, I went back to the beginning: No sound. No matter w= hether I restart with headphones unplugged, I haven't been able to get the = sound device to be recognized again. --- https://sirgazil.bitbucket.io/
