Description Andreas Tunek 2007-08-02 14:15:56 UTC
Description of problem:
There is no sound from the speakers or the line out when you run F7 on a 24 inch

Version-Release number of selected component (if applicable):
[root@localhost tuna]# yum list alsa*
Loading "installonlyn" plugin
Installed Packages
alsa-lib.i386                            1.0.14-1.fc7           installed       
alsa-utils.i386                          1.0.14-1.fc7           installed   
[root@localhost tuna]# yum list kernel
Loading "installonlyn" plugin
Installed Packages
kernel.i686                            installed       

How reproducible:

Additional info:
This was supposed to be fixed in 1.0.14 (se bug 244104,
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=244104), but was not.

There is a thread in Ubuntuforums with a patch (here is the relevant post:
http://ubuntuforums.org/showthread.php?t=418681&page=5 )

Comment 1 Andreas Tunek 2007-08-11 19:30:28 UTC
Tested with the F8t1 live CD as well, no sound there either.

Comment 2 Martin Stransky 2007-08-13 08:58:19 UTC
Yeah. So you need to patch 1.0.14 drivers (by udiff-patch_realtek.txt). 

Please report that to upstream (www.alsa-project.org, just open a bug there) and
they should do that. We use alsa-drivers from stock (vanila) kernel. We don't
patch ALSA in our kernel for Fedora. 

So if you want this support in fedora, please push it through alsa project. Thanks.

Comment 3 Andreas Tunek 2007-08-14 16:24:48 UTC
Actually, I made a mistake and it seems that the version of ALSA in F8t1
actually is patched. I couldn't hear anything because the default volume is to
low. Raising the volume you can hear things clearly though. So bug closed!
