FC16 sound or no sound, that is the question.

Still trying to get sound when using Xine. I know the hardware works because XP does fine with it.
I reconfig part of the sound system build for 3.3.3 kernel and re-boot. Sound works. I shutdown and
run Xine again and no sound.

I also tried a config with the entire group of sound modules built. Pretty much like the way a pre-built
kernel is. No sound.

I also try released kernels but same thing.

$ lspci | grep audio
00:1f.5 Multimedia audio controller: Intel Corporation 82801EB/ER (ICH5/ICH5R) AC'97 Audio Controller (rev 02)

The motherboard has the ADI1985 6-channel CODEC.
Just wondering if others see behavior like this.
Usually happens that when a FC release becomes stable for me a new release is available and I start all over again.

Re: FC16 sound or no sound, that is the question.

I found out what is going on.
I build a kernel and make the modules and install.

$ ls -l /lib/modules/3.3.3/kernel
total 24
drwxr-xr-x. 2 root root 4096 Apr 25 04:42 crypto
drwxr-xr-x. 11 root root 4096 Apr 25 04:42 drivers
drwxr-xr-x. 10 root root 4096 Apr 25 04:42 fs
drwxr-xr-x. 2 root root 4096 Apr 25 04:42 lib
drwxr-xr-x. 3 root root 4096 Apr 25 04:42 net
drwxr-xr-x. 5 root root 4096 Apr 25 04:42 sound

I reboot and run speaker-test, works ok. But the tones
appear to be switching between two different drivers.
After a few iterations between right and left speakers the
tones coming from the speakers are contiuous and that is
when the sstem decides to remove the "sound" modules
directory.

I have even removed write permissions all through the sound
directory, but it still is removed by the running system. The next
reboot and then there is no sound driver loaded. I have to
install the modules again.

Does anyone know why this happens. I disabled PC-Speaker
support but nothing changes. I think this behavior can affect
other people who just use the normal updates method.

I see that "sound" is being replaced by "oss" in /lib/modules/3.3.3/kernel.
I looked at previous posts on the net and some go back to 2006 with
this problem.

What I did was rebuild the kernel with my sound driver part of the kernel
and not as a loadable module. Problem fixed for sound. This should work
for other people who say their sound disappeared.
