Description Robin Green 2004-02-27 22:32:30 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.6)

Description of problem:
Even after unmuting and setting the master volume and the pcm volume
in alsamixer, I can still not get any sound out of any application.

I have tried:

mplayer -ao alsa9 test.mp3 - does not complain, appears to work but no
mplayer -ao oss test.mp3 - does not complain, appears to work but no sound
mpg321 test.mp3 - does not complain, appears to work but no sound
esd - segfaults when I try to run it
xmms - segfaults when I try to run it
noatun - opens, but silently refuses to play test.mp3
cat /dev/urandom > /dev/dsp - no sound

Also, the KDE sound server gives the error ending with "the sound
server will continue with the null output plugin" when I log in.

I have also tried compiling kernel 2.6.3 - no difference. Tried
different values of dxs_support option in modprobe.conf - no difference.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Run redhat-config-sound
2. Adjust mixer settings with alsamixer
3. Play test song


Actual Results:  Test song fails

Expected Results:  Test song succeeds

By the way, I know the hardware (it's an onboard chipset) physically
works in some sense because there is a loud beep out of the speakers
on every boot-up.

Comment 2 Robin Green 2004-02-28 16:42:22 UTC
Just tried the OSS driver with my self-compiled kernel 2.6.3. It works

Comment 3 Arjan van de Ven 2004-03-10 17:12:34 UTC
are you aware that alsa defaults to a sound volume of 0? please run
alsa-mixer to increase the volume

Comment 4 Robin Green 2004-03-10 18:22:38 UTC
I am aware of this. The very first line in my bug report starts: "Even
after unmuting and setting the master volume and the pcm volume
in alsamixer..."

I am also see this problem (ASUS SK8V with Opteron 140).

The hardware works fine when I bootup FC1 x86_64 but it does not work
with FC2-Test2.


When I try to bring up volume control (the appl) I get a popup message
that says "No mixer elements and/or devices found".

Yes, /dev/mixer exists and all the modules appear to be loaded.

Hi Robin! I had similar problem, but without segfaulting. Maybe this
wiil help you:

Comment 7 Dave Jones 2004-12-07 05:48:19 UTC
fixed in the current errata kernel ?

Comment 8 Gene Czarcinski 2004-12-07 05:55:43 UTC
I will leave this for someone else to address since I have since
replaced the sound adapter I am using.

Comment 9 Wes McGee 2004-12-12 14:52:47 UTC
"fixed in the current errata kernel ?"
Not for me, at least. I'm also not getting any sound from that same
sound adapter, and I had upgraded to 2.6.9-1.681_FC3 through that
up2date and did all the things Robin Green did in the beginning of
this bug report.

Comment 10 Dave Jones 2005-04-16 06:07:10 UTC
Fedora Core 2 has now reached end of life, and no further updates will be
provided by Red Hat.  The Fedora legacy project will be producing further kernel
updates for security problems only.

If this bug has not been fixed in the latest Fedora Core 2 update kernel, please
try to reproduce it under Fedora Core 3, and reopen if necessary, changing the
product version accordingly.

Thank you.
