Red Hat Bugzilla – Bug 506736
No sound from device CS4236 under F10
Last modified: 2009-12-18 04:34:23 EST
Description of problem:
After a fresh F10 install with updates as of 2009-09-18 and kernel-220.127.116.11-84.fc10.i686, no sound is available from the CS4236 device of my PR440FX desktop system. This ISA PNP device is properly recognized, and the corresponding modules are loaded. However, no sound comes from the audio system which is working correctly when booting W2K instead.
Utility 'pavucontrol' claims that no hardware devices are available and falls back to using null devices instead, but /proc/asound is definitely populated since 'ls /proc/asound' returns
card0/ CS4236B@ hwdep oss/ seq/ version
cards devices modules pcm timers
Moreover, 'alsamixer -c 0' returns "wrong -c argument '0'" when run as ordinary user but brings correctly up the audio panel when run as root. Unmuting channels and increasing sound levels has no effect though.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Launch GNOME session.
2. Enable sound effects or play WAV file by means of aplay.
Sound effects work as expected.

This message is a reminder that Fedora 10 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 10. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '10'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 10's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 10 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora please change the 'version' of this
bug to the applicable version. If you are unable to change the version,
please add a comment here and someone will do it for you.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
The process we are following is described here:
Fedora 10 changed to end-of-life (EOL) status on 2009-12-17. Fedora 10 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version.
Thank you for reporting this bug and we are sorry it could not be fixed.
