[gentoo-user] Kernel upgrade, no sound.

[gentoo-user] Kernel upgrade, no sound.

[Dale]

Hi,

I upgraded my kernel the other day and now I have no sound at all.  I
have checked Alsamixer and Kmix to make sure it is not muted and it
appears to be turned up there.  This is lspci:

> 01:0a.0 Multimedia audio controller: Creative Labs SB Live! EMU10k1
> (rev 0a)

I have this built into my kernel:

> <*> Emu10k1 (SB Live!, Audigy, E-mu APS)

I copied my old .config over and did a make oldconfig but it has the
same setup as before.  I just don't have any sound at all.  I did make
sure my speakers are powered on, plugged into the puter and everything I
checked says it is unmuted.  Maybe I missed one though.

The kernel version that works is gentoo-sources-2.6.18-r6, the one that
does _not_ work is gentoo-sources-2.6.20-r8 if that will help.

I did boot my old kernel, the 18 version, and the sound works fine.  If
I boot the new 20 version, nothing.  Kernel problem or am I missing
something?

Any ideas?  Thanks much for the help.

Dale

I had a similar thing, no sound with any kernel after .18

My card is not the same as yours so my exact solution won't work for 
you. What I did was note which modules were loaded, then run alsaconf 
and let it do it's thing. Note which new modules it loaded and put 
those in /etc/modules.autoload.d/kernel-2.6

It appeared to be that the modules dependency information changed with 
my driver around .18 and the earlier config just didn't cut it anymore. 
Of course, I could also be completely wrong :-)

Thanks for the info but I build everything in the kernel.  I never liked
modules.  I suspect that something did change about the kernel though. 
I may just stick with the older kernel for now and try another version
later.

Still open to ideas though.

Thanks

If you post the output of this command:
lspci -s 01:0a.0 -n
We will have the PCI id to search for. Might make it easier to find bug 
reports.

The output of this command:
dmesg|egrep -i -A3 "(alsa|sound)"
Should give us an idea of whether your kernel actually detects your sound 
card.

Well, you won't believe this but I rebooted into the newer kernel to get
the info for you, now it works fine.  O_O  I have sound when I change
desktops, it plays a CD fine, it seems to be working now.

Just for the sake of anyone who may can use this in the future:

If it stops working I'll let you know.  I guess it just wanted me to ask
for help.

Thanks much!!

That's so great. I couldn't find any reason why it would NOT work either from 
your posts, so I guess this was just a Go Away bug. Leave the computer, come 
back. It's gone.
