http://bugzilla.opensuse.org/show_bug.cgi?id=1205640 http://bugzilla.opensuse.org/show_bug.cgi?id=1205640#c19 --- Comment #19 from Antonio Larrosa <alarrosa@suse.com> --- That's very interesting and makes me think it might be a case of the kernel powering the usb device down due to power management. You can test this by running "sudo powertop" (install powertop if you don't have it in your system). Inside powertop, press TAB a few times to go to the "Tunables" tab. Search there for your audio devices (using arrow up and down) . It will probably be in "Good" state (please, confirm it). "Good" means the device will have enabled power management (in other words, it will be autosuspended when not in use). Some devices are not compatible with this and will misbehave, which might be the case for your audio device. Press space to change it to "Bad" (disable power management). Press ESC to leave powertop. Then check if you can reproduce the problem. Note that a system reboot will restore the original state, so you'll have to repeat the process to turn autosuspend off again. Btw, it's safe to turn all devices to Good/Bad if you want to make tests, but beware that sometimes keyboards/mice stop working if you enable autosuspend on them. -- You are receiving this mail because: You are on the CC list for the bug.
