A couple things: Make sure the volume is turned up on all mixer devices--either run "alsamixer -c0" from a terminal to bypass the PulseAudio mixer and control the underlying ALSA device, or right-click the volume control icon in the GNOME menu bar and click "Open Volume Control". Also, right-click the volume control icon and go to Preferences to set the which sound card and mixer slider the icon controls. Finally, check the PulseAudio volume control in Applications->Sound and Video->PulseAudio Volume Control. If you have more than one sound card (USB headset, onboard vs. PCI sound card, etc.) make sure PulseAudio is set to use the "right" one by default by right clicking the Output Device and selecting Default. If you leave the PulseAudio volume control open while trying to play sounds and music, you should see each application show up under Playback. You can move the streams between different output devices on-the-fly, control their volumes independently, etc. If you still can't get sound, try temporarily bypassing PulseAudio to see if the underlying ALSA device works: As root: su - mv /etc/alsa/pulse-default.conf /root exit As a normal user, stop the PulseAudio daemon: killall pulseaudio Try a sound application, setting its output device to ALSA instead of PulseAudio. Bear in mind that the PulseAudio daemon may try to respawn if you attempt to use an application that is set to PulseAudio or ESD/ESound output. You may have to "killall pulseaudio" again. After testing, move the file back: su - mv /root/pulse-default.conf /etc/alsa/ exit If you have a SoundBlaster Live! or similar card that uses the emu10k1 ALSA driver, there is a known issue with hiccups etc. when playing music through the new PulseAudio "Glitch-Free" plugin. The bug is actually in the ALSA emu10ki driver but doesn't show up under the older PulseAudio or non-PulseAudio cases since only the new PulseAudio "Glitch-Free" code uses the driver functions/APIs that are buggy. There may be problems with some of the other drivers too, such as Intel HDA (snd_hda_intel). https://bugzilla.redhat.com/show_bug.cgi?id=462026 I've had luck downgrading the Fedora 10 pulseaudio plugin to the Fedora 9 one which doesn't use the new "Glitch-Free" stuff: 32-bit: rpm -Uvh --oldpackage http://download.fedora.redhat.com/pub/fedora/linux/releases/9/Fedora/i386/os... 64-bit: rpm -Uvh --oldpackage http://download.fedora.redhat.com/pub/fedora/linux/releases/9/Fedora/x86_64/... Finally, I encourage you to try the above steps to make PulseAudio work before going this route, but if you want to give up on PulseAudio altogether, you can disable it by removing this package: yum remove pulseaudio You won't have sound mixing, per-application volume controls, on-the-fly audio stream moving between output devices, etc. but it might work better for you until some of the ALSA kernel driver bugs are fixed.

I, too, have found that after an upgrade to Fedora 10, the sound on my laptop stopped working. Any ideas? Walt

I decided to install fedora 10. I understand that my laptop is old (bought in 2002). Fedora 8 had problems installing due to 256M of ram but ran fine once I got it installed. I've since upgraded the memory but fedora 10 can't play audio. Any music file I've tried lags horribly. Is there any configuration I can modify to fix the problem? Alternatively can the audio server be disabled?
