I am using F18 + KDE on a notebook. I have an nvidia video card (GeForce GTX 560M) which inclues HDMI support but I am not using the HDMI output, only the internal screen and speakers. On F17, everything was fine. On F18, the keyboard volume buttons (stop, more, less) do not work anymore. I can see the box with percentage changing and sound/no sound icon but it does not do anything. Also, when I click in the panel volume icon (KMix), I can see that HDA nvidia digital stereo (HDMI) is selected but I do not want to use that one, I want to use the internal speaker. Also, pluging a headset do not work properly. In KMix control panel, I see that HDA NVidia is selected for "sound card" but if I choose Internal audio, it comes back later to HDA NVidia. I do not know what to do to have this working normally. I see from another thread that maybe this could be related to pulseaudio. It seems pulseaudio is not working for me: $ pulseaudio --check gives empty output. $ ps ux|grep puseaudio gives nothing either (as root) Any help would be appreciated. Thanks, Frédéric
