results from 0.4.63 alsa-info run
Speakers were "activates", by a method described in this report, when this script was running.

essential differences in alsa-info output between broken and unbroken sound
This diff is for equally broken 3.15.5-200.fc20.x86_64 kernel. The first run of alsa-info was after a reboot with no sound on speakers and the second after plugging and unplugging headphones to restore a speaker sound.
vmlinuz-3.17.1-304.fc21.x86_64 Sound cards are not detected. Dummy card shown Previous version vmlinuz-3.17.1-303.fc21.x86_64 both sound cards detected, sound works. (In reply to Leslie Satenstein from comment #3) > vmlinuz-3.17.1-304.fc21.x86_64 > > Sound cards are not detected. Dummy card shown Would you, please, open another bug targetting Fedora 21 instead of 20? As a matter of fact with the current F20 kernel-3.16.6-200.fc20.x86_64, and likely earlier as well, that particular bug from the original report is gone. Regrettably I have no idea what actually fixed that but the fact remains that this is now ok (although, for example, skype still does not want produce sound for me on 64-bit F20 installations while it worked fine in the past). |
