Additional info: https://bugs.helixcommunity.org/show_bug.cgi?id=7375 https://bugtrack.alsa-project.org/alsa-bug/view.php?id=2601 http://forums.fedoraforum.org/showthread.php?t=186200 Some have reported that this may be result of a bug in alsa-libs. The alsa-bug report # 2601 reports possible fixes for this which may not hove gotten through in Fedora 8. leigh123@linux reports in Fedora Forum that RealPlayer was crashing in Fedora 9 but is now working.
I found a fix here: http://forums.fedoraforum.org/showthread.php?t=174298&goto=newpost Here's what I did. # rpm -e RealPlayer # yum install kernel-devel mercurial # yum groupinstall 'Development Tools' $ hg clone http://hg-mirror.alsa-project.org/alsa-driver alsa-driver $ hg clone http://hg-mirror.alsa-project.org/alsa-kernel alsa-driver/alsa-kernel $ cd alsa-driver $ make ALSAKERNELDIR=alsa-kernel all-deps $ aclocal; autoconf $ /configure --with-cards=hda-intel $ make || make # make install Then reboot to make sure you're using the newly compiled module. Then simply: Answer for 1. cd to where you downloaded RealPlayer 11 and # rpm -ihv RealPlayer11GOLD.rpm and it just works. Right out of the box. Default settings. In Firefox RealPlayer plugins play streaming audio fine streaming video seems buggy but this report is for audio issue and that's working fine. Answer for 2. $ speaker-test speaker-test 1.0.15 Playback device is default Stream parameters are 48000Hz, S16_LE, 1 channels Using 16 octaves of pink noise Rate set to 48000Hz (requested 48000Hz) Buffer size range from 2048 to 16384 Period size range from 1024 to 1024 Using max buffer size 16384 Periods = 4 was set period_size = 1024 was set buffer_size = 16384 0 - Front Left Time per period = 2.659716 0 - Front Left 3. Now MPlayer plays music videos just fine. This with MPlayer>Preferences>Audio> set to and >Video set to xv. Credit for this fix goes to poster nikosapi at this link: http://forums.fedoraforum.org/showthread.php?t=174298&page=3&pp=15
Whoops. I left one thing out. I also had to uncomment the line "/etc/alsa/pulse-default.conf" in '/etc/alsa/alsa.conf': # # ALSA library configuration file # # pre-load the configuration files @hooks [ { func load files [ # "/etc/alsa/pulse-default.conf" "/etc/asound.conf" "~/.asoundrc" ] errors false } ] # load card-specific configuration files (on request) cards.@hooks [ { func load
Can you please check if is it present in Fedora9? There are some audio config changes there.
Moving to pulseaudio...
This is being fixed in RealPlayer. There could be a problem with alsa-lib too; see comment in this bug report: https://bugtrack.alsa-project.org/alsa-bug/view.php?id=2601 But this is not a PulseAudio problem though.
*** Bug 445106 has been marked as a duplicate of this bug. ***
I am pretty sure this was fixed a while back in alsa-lib. Closing. If the problem persists, please reopen.
