FC6 no sound output using cx88-alsa
Last modified: 2007-11-30 17:11:47 EST
Description of problem:
I did a clean install of the final release version of FC6 today... sound is no
Using FC4 and FC5, sound did work using the cx88-alsa module; no hardware has
I'm running the current i686 kernel for FC6; I had to manually remove the i586
kernel after install and replace it with the correct i686 kernel.
I've tried to modprobe cx88-alsa a few times, and have rebooted several times...
surprisingly, I did get sound to work in Totem ONCE only. After rebooting, no
more sound again, and 'modprobe cx88-alsa' no longer works.
Version-Release number of selected component (if applicable):
------ rpm -q alsa-lib --------
------- rpm -q alsa-utils --------
Steps to Reproduce:
scsconfig.log is attached, as the Soundcard Detection tool requests.
Please let me know what other info I can provide! Thanks!

One more thing to add...
After rebooting again, sound still didn't work. modprobe cx88-alsa still didn't
** If I play a flash animation using Adobe Flash 9 Beta, sound DOES work. Only
after this happens, sound will continue to work in Totem.
Despite both of these things still functioning, I'm still getting most sound
events thru the PC speaker. For example, if I hit tab a few times in a bash
shell, I get an old PC speaker beep.
So something is clearly still not working properly. I have no idea how to
explain what Flash 9 is doing.
Sorry - I can't reproduce this. Rebooting, trying modprobe again, and running
flash did not restore sound.
This must have been a coincidence. I have not found the reason why sound was
restored previously (flash doesn't appear to have done anything, which makes
You have two cards, the first one is:
00:04.0 Multimedia audio controller: nVidia Corporation CK804 AC'97 Audio
Controller (rev a2)
and the second one:
01:06.0 Multimedia video controller: Conexant CX23880/1/2/3 PCI Video and Audio
Decoder (rev 05)
01:06.1 Multimedia controller: Conexant CX23880/1/2/3 PCI Video and Audio
Decoder [Audio Port] (rev 05)
01:06.2 Multimedia controller: Conexant CX23880/1/2/3 PCI Video and Audio
Decoder [MPEG Port] (rev 05)
Which one would you like to use?
The first one would be better... it's the integrated sound card.
Changing version to fc6 from test3.
Could you please check the latest drivers / packages? (ALSA 1.0.14rc1)
