Red Hat Bugzilla – Bug 232899
sound problems (hda-intel and kernel > 2.6.18)
Last modified: 2008-05-06 15:22:41 EDT
Description of problem:
On an ACER (Ferrari 1000) and FC6-X86_64, with the kernel 2.6.18-1.2798 I can
hear the sound but when I updated the kernel to 2.6.19 or 2.6.20-1.2925 there
is not sound.
Actually with the kernel 2.6.20-1.2925 and all the components updated, I can
hear the sound test of system-config-soundcard only with the left headphone.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
Can you please check packages alsa-lib-1.0.14, alsa-utils-1.0.14 from devel or
from my test page? (http://people.redhat.com/stransky/alsa/)
After updating alsa-lib and alsa-utils to 1.0.14-0.1.rc1.fc6, the problem remains
even worse (no sound on the let headphone)
I've asked you to update to rc3/rc2, 1.0.14-0.1.rc1.fc6 are packages from fc6.
the problem remains, there is not sound even on the left headphone
Please note that
solve a similar problem (bug #231414 ) on a chip ATI SB450 but
the Acer Ferrari-1000 has an ATI RS485
Can you please attach /root/scsconfig.log? (it's generated by
system-config-soundcard, on the "System" page)

You have installed user-space packages alsa-lib-1.0.14-0.1.rc3,
alsa-lib-1.0.14-0.1.rc1.fc6 and kernel drivers 1.0.14rc1.
So please remove your user-space packages, check my page
(http://people.redhat.com/stransky/alsa/) and install the rc4 ones (kernel,
alsa-lib and alsa-utils packages).

new scsconfig.log file after the changes
After doing that, the problem remains.
Please find attached the new scsconfig.log file
(Note that although I have installed the alsa-driver-1.0.14-60_rc4.fc6 ,
alsa-kmdl-2.6.20-1.2948.fc6-1.0.10-60_rc4.fc6 it appears the alsa-driver
1.0.14rc3 in the scsconfig.log)
yep, you still use the 1.0.14rc3 driver.
please try to compile it by yourself, from tarball (but I'm not sure if it
really helps you)

I have compiled from tarball the alsa-driver-1.0.14rc4, and installed
with make , make install but the 1.0.14rc3 driver is there and it appears again
in he scsconfig.log ¿what is wrong?.
did you reboot your box?
(In reply to comment #12)
> did you reboot your box?
yes, several times.

new scsconfig.log (with the driver 1.0.14rc4)
After the compilation of
alsa-driver-1.0.14-60_rc4.fc6 , make install puts the drivers in
whereas the system loks at /lib/modules/2.6.20-1.2948.fc6/updates/sound
So I copied /lib/modules/2.6.20-1.2948.fc6/kernel/sound to
and now system-config-soundcard recognizes the 1.0.14rcd drivers.
But there is not sound. I send you the new scsconfig.log file
Can you please check the latest drivers? (1.0.14 final, from

new scsconfig.lof file with the asla-driver-1.0.14 and alsa-lib-1.0.14a-0.6
No sound again. Please find attached the new scsconfig.log file.
I suspect that all is due to a problem with the 64bit kernel. In fact
there is some one who claims that has not problems with the sound on an Acer
Ferrari 1000 with ubuntu-7.04 and that has installed the official WindowsXP
Ferrari 1000 wlan broadcom driver using ndiswrapper
(rbak.demon.nl/ubuntu/acer_ferrari.php). But when I try to install the same
driver I get a message:
--kernel is 64 bit, but Windows driver is not 64-bit.
-- couldn't load driver bcmwl5
So, surely he (she) has installed the 32 bit kernel.
hm. I'll move it to kernel because it looks like a regression there. It would be
great if you can confirm that the old kernel still works fine for you.
Latest kernel is now 2962, was that tested?
1) Ruurt Bak (see rbak.demon.nl/ubuntu/acer_ferrari.php) has not problems with
the sound but he told me that he is using the ubuntu 32-bit version.
2) Another user told me that he is using his own compilation of the 2.6.20-1.2952
64-bit kernel and that has sound
So probably the problem is on the Fedora rpm that has mis configured somthing ?

Was that one tested? Major Intel hda fixes went into that version...
With the 2.6.20-1.2962 fedora kernel, things are even worse.
I have re installed the alsa-1.0.14 drivers (since the redhat kernel comes with
the oldest .rc1 version). Please see attached the new scsconfig.log file.
Now I can't use the camera even after recompiling the gspcav1 drivers and the
spcaview fron Michael Xhaard which worked normally with the 2952 kernel.
By the way, there is another problem with the wifi because the windows driver
for the amd_64 uses more memory than that of the fedora kernel so ndiswrapper
gets out of memory (but as I have seen on the net this is a general problem with
fedora an the windows drivers that need more than 4M).
