Here is a way to check your system directly through alsa. From your previous output, alsa is recognizing your card, so it should play properly. If it does, then the issue is in the controls that are applied after alsa. Install the package pavuctl, the pulseaudio volume control, if you haven't already. Open it (Sound & video -> Mixers -> PulseAudio Volume Control on Gnome F14) Go to the last tab, configuration. >From the drop down selection for profile, select Off. Now open a terminal in X or go to a console. Type the command alsamixer and check that all the outputs are turned on and have appropriate level. Esc exits. Type the command aplay -Dplughw:0,0 <some wav> replacing <some wav> with a wav file name. Given the values you showed in amixer, this should play sound. If you want to be doubly sure, use a sound player that shows the output visually (audacity, xmms, audacious) instead of aplay. Make sure you configure it to use alsa instead of pulseaudio before you try. If it doesn't, there has probably been a regression in the driver for your card, and you should open a problem ticket with alsa. If it does, the problem is in pulseaudio / gui configuration of sound. I suggest you then play with the volume control in PulseAudio, and use only pulseaudio (turn off any gnome or kde sound control) until you have sound again. PS You definitely have an output device (speakers, headset) connected? PPS There is a script at the alsa website (http://www.alsa-project.org) called alsa-info.sh that will give huge amounts of information about your sound system and configuration. It seems you already have lots, but it might give an additional hint. -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
