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.

mixer volume seems to be right up

... and I don't appear to have /sbin/alsa/reload


Thanks for responding, though

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.

Alan

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
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.
You may want to check this with both kernels and see what (if anything) is different.

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

and this is the one that does work:

Oh, did I say, the soundcard is an Audigy 2 ZS

... annd the alsamixer shows output up in the red?

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

And check if any of these suggestions work for you.

Good luck,

and today, it works! Go figure, as they say. Thanks very much for your patience, Laserman.
