Sound Card Problem in FC 6 --- Really Wierd Issue

animeshsaxena · 05-15-2007, 06:41 PM

I have two operating systems installed -- Windows 2000, Fedora Core 6.

The sound card sometimes works and sometimes doesn't. The amazing part is that always the module is initialized properly, just the sound doesn't come

. Then I noticed something strange. When I start windows and shut it down abruptly (No proper shutdown), then when I start Fedora the sound works perfectly. But if I shut it down proprly (Windows 2000) then the sound does not come. In both the cases module is loaded. Might be windows is turning of some setting that Fedora is not able to turn back on.

I am using Compaq V3155AU Laptop, with Connexant HD Audio system.

I also tried the latest version of ALSA Mixer hopin that volume control is not able to initialize properly. But I guess Fedora is not able to turn on the setting even after loading the module. Sound card Module loaded is "snd-hda-intel".

Any ideaz on this one????

Thanks for the help. Could solve the sound problem by installin new kernel 2.6.18-1.2798.fc6.stk16-i686
But now when I tried to compile programs like driverloader or ndiswrapper I get a floating point exception kinda error. Is there any patch for that....

Well it may be easier to use the standard kernel from FC6 and install the dkms-ndiswarrper pacakge from freshrpms.net;

yum install dkms-ndiswrapper

This of course requires a working Internet connection and the freshrpms-release repo enabled;

http://zod.freshrpms.net/

rpm -ivh http://ftp.freshrpms.net/pub/freshrp....fc.noarch.rpm

yum install dkms-ndiswrapper

By hand, download the dkms-ndiswrappr rpm package and also the dkms rpm package from Fedora Core 6 extras. You will need to have the matching (by kernel version number) kernel-devel and kernel-headers rpm packages installed:

http://download.fedora.redhat.com/pu...inux/extras/6/

Then as root from where the two rpm packages are type: rpm -ivh dkms*.rpm
