1. Do you still have pulseaudio installed
*fedora is completely dependent on Pulse for sound almost.
2. is pulseaudio running in the process id
go to applications->system monitor and search for it.
3. run lspci and post the output
and post the output here.... lspci shows vital hardware information
4. if you have an onboard sound card and and installed card make sure the onboard is disabled if you are using an installed card vs onboard, also make sure your speakers are connected the right outputs.
5. try alsa mixer to make sure it has not been muted
make sure <front> and <pcm front> and <pcm> are at 100 %
alsamixer -c <cardnumber>
<cardnumber> is usually 1 or zero. if pulse audio shows up as a device make sure it is at 100 volume level and then move to the next number
till your card shows up exclude < >
to exit alsa mixer press Esc
... after words to exit terminal type exit and hit enter.
6. Try the digital / analog out settings, that causes sound loss too. that had been an issue in previous fedora for me, but not fedora 11 and 12 for me.
* if you left alsamixer restart it with the proper card number then press f5
then click the left arrow until you see in Analog/Digital ouput jack and toggle it using m. DO NOT CLOSE out alsamixer at this point test your sound if it does not work still then you best untoggle it before you close out... by pressing m again.
7. you need to install pavucontrol
su -c 'yum install pavucontrol'
it is very powerful utility for managing sound
the installed app will be found in Applictions -> Sound & Video -> Pulse Audio Volume Control
it allows you to select Ouput Devices, Input Devices, Recording levels. and adjust volume.
