fedora 10 update seems to nuke my sound


It happened once with Fedora 9, I upgraded to 10, and now it's happened again. I assume it's the automatic update, because I haven't changed anything else - suddenly no sound. This is kernel 2.6.27.12-170.2.5.fc10.x86_64. If I go back to 2.6.27.5-117.fc10.x86_64, the sound is back again. I'm sure I'm missing something obvious, but would really appreciate some help.

Also, the settings for Alsa mixer and for PulseAudio volume control are the same for the kernel that works and the one that doesn't.

Hi Alan,
/sbin/alsa reload is a command to be typed in a terminal.
Open a terminal window and type 'su -' without the quotes to become root.
Type in the root password when prompted.
Type in '/sbin/alsa reload' without the quotes to restart the alsa program.

Others have also had this problem. If the reload doesn't help you can boot with the old kernal until a fix comes along.

Thanks, Laserman,
I don't have /sbin/alsa, all that seems close is /sbin/alsactl, and reload doesn't work with that. I guess I'll stick to the older kernel, but should I refuse updates, and how will I know when a fix comes along?
Sorry to spout so many questions. Good to know I'm not alone - well, good to know I'm not an only dumb one, and that others get this too.

Hi Alan,

It's not a good idea to refuse the updates as they may fix things far more serious than missing sound such as security holes.

If alsactl reload didn't work you may want to try
Code:
# alsamixer
which will give you a graphical display of the volume setting.

btw: when posting outputs of things like 'lspci' and 'lsmod' surround the info with:
[ code ] and [ /code ] (without the spaces)
This will format the output nicely and make it much easier to read.

Here is the output of 'lsmod | grep snd' from my system.
Code:
[root@localhost /]# lsmod | grep snd
snd_via82xx            25752  3 
snd_ac97_codec         95268  1 snd_via82xx

snd_seq_device         10124  4 snd_seq_dummy,snd_seq_oss,snd_seq,snd_rawmidi

gameport               13452  3 snd_via82xx,ns558
soundcore               9416  1 snd
You may want to check this with both kernels and see what (if anything) is different.

soundcore              14992  1 snd
like this,I hope? Doesn't mean anything to me, I'm afraid - this is the later kernel, where the sound doesn't work. Thanks for your patience,

Alan

They look identical to me Alan. It's definately a kernel issue.
