mixer cannot be found after Kubuntu 8.04 upgrade

[John Cottier]

Binary package hint: alsa-base

After a upgrading from Gutsy to Hardy, the sound was fine for a day, then it vanished and the kmix applet report "Mixer cannot be found". Alsa does not appear exist any more. Alsa-base is still installed. Running sudo alsa reload :-
Unloading ALSA sound driver modules: (none loaded).
Loading ALSA sound driver modules: (none to reload).

Please let me know what debug information is needed.

Hi Richard, Files are attached. Its probably just coincidence, but the sound seemed disappear at the same time as I added linux-restricted-modules-2.6.24-xx-386 manually in an attempt to fix the restricted driver issue. Also, if I run alsamixer in the console is gives:- alsamixer: function snd_ctl_open failed for default: No such file or directory. But the card driver emu10K.. module is still loaded. (standard Creative SB Live).

Can you take a look at bug #205108 and see if your issue is the same?

Thanks,

Richard Seguin

No, I don't think so. lsmod (attached) shows the emu10k module loaded, and lspci shows the card detected. It just seems to be alsa thats gone awol.

[John Cottier (john-cottier)]

It seems only the games port is being detected, because the emu10k1 module has vanished!
(sound tested and still working on a live CD)

john@John-Linux:~$ sudo modprobe snd-emu10k1
FATAL: Module snd_emu10k1 not found.

john@John-Linux:~$ find /lib/modules/`uname -r`/ | grep emu10k1
/lib/modules/2.6.24-16-386/kernel/drivers/input/gameport/emu10k1-gp.ko

How can I reinstall the emu10k1 modules?

[John Cottier (john-cottier)]

Fixed! It turns out that it was not a coincidence that this happened after I installed linux-restricted-modules-2.6.24-xx-386. It appears this also made the system pull in the kernel 2.6.24-16-386 instead of the 2.6.24-16-generic and modified the grub menu.lst. Presumably the .386 kernel does not have the emu10k1 driver enabled by default.
I tried selecting the generic kernel from the boot menu, and the sound now works again. So I have removed all .386 image and related bit and restored the old grub menu.lst. I seem to have 4 versions of kernel accumulated now. Easy it easy to remove these, or does it mean manually amending the grub menu?

Setting to invalid as it is not a bug

Mplayer is not working. Alsa mixer is not loading, although sound works in genenral I have no control on kmixer, and cannot load alsamixer.
