Red Hat Bugzilla – Bug 275611
Sound has not worked on my system since Fedora Core 5
Last modified: 2008-02-24 10:32:49 EST
Description of problem: I have a Dell 8300 with a emu10k1x sound card. The
sound works just fine on a FC5 partition buy not on a Fedora 7 partition with
the latest maintenance applied to all software.
Version-Release number of selected component (if applicable):
How reproducible: Try to use sound detection component or other sound software
and sound will not come out of speaker on Fedora 7. If I boot the system to a
FC5 partition sound will play just fine.
Steps to Reproduce:
1. Select sound detection
2. Set to back plugin for speaker wire, set to repeat, and press play button.
No sound plays
Sound to play
Additional info: Here is the scsrun.log and I have attached the scsconfig.log:

Cay you check the "alsamixer" utility and try to enable/unmute some channels.
It looks like a problem in drivers/kernel. If that alsamixer doesn't work for
you, you may report it to ALSA project (www.alsa-project.org).
I have spent a lot of time on this. Yes I had checked the controls in alsamixer
from root and tested different changes. I did some additional testing and
I wrote down the settings in Fedora 7 and compared them to FC5. There are
several differences. The main one from what i can see is that FC5 has a PCM and
a PCM Out control. Fedora 7 only has a PCM control and not PCM Out control. I
did some searches on the net and I could not find anything relavant for a PCM
Out control missing in Alsamixer. Should a PCM Out control be showing up in
Alsamixer on F7?
I will proceed to submit a bug to the Alsa project in the next few days.
Thank You for your help.
I was hoping you would respond to the question. Should a PCM Out control be
showing up in Alsamixer on f7?
Could you tell me what level of alsa-drivers is in Fedora 7.91 (Fedora 8 Test
Level 2). I load it up but I still have the problem. With updates that gave me
newer 1.0.15 levels of alsa-lib and alsa-utils.
The latest available ALSA is 1.0.16. The current ALSA in F8 is 1.0.15.
Unfortunately s-c-s was removed from F9 and it's not going to be developed.
Closing as wontfix.
If you have any hardware support issue, please file it against kernel.
What is s-c-s?
OK - s-c-s means system-config-soundcard
