This bug is the same as bug #422696 and the reason is that OSS has been
deleted from Maverick's kernel (bug #613809). I had fixed it as said on
that bug (the last).

[Bug 637339] Re: After upgrading to Ub 10.10, no /dev/mixer!

[...]

forgive me ... i am a little bit wrong here.

after upgrading from 10.04 to 10.10 i had these mixer problems so i
tried to downgrade back to 10.04. but  i make many mistakes.

since i am "new" to linux and not beeing very familar with it in detail,
i decided to try out debian which uses kernel 2.6.26-X-686 and found
same mixer problems there. my idea was that my modprobe idea could also
be helpful on kernel shipped with ubuntu, even if i didn't install
ubuntu again to test it.

elsewhere i can read that ubuntu developers removed different sound-
things from current kernel. many users had tears in their eyes as i can
see from results in search engines.

As mentioned, I have also discovered that the GUI mixer was calling the
show. Without a /dev/mixer to
work with, neither gnomeradio or kradio's sound volume controls work at all.
But you can control the volume
from the mixer utility. If you want to turn the radio down and listen to
something else, well, kill the radio
program. And make sure it does a mute on exit.

I've tried to do the modprobe, but I get

FATAL: Module snd_mixer_oss not found.

I put in the dashes as you described. I searched the system for
snd-mixer-oss,
but the only ones I find were from older kernel versions (2.6.27-7,
2.6.28-11,
2.6.32-24). I do "apt-cache search snd-mixer-oss", and no go. Can you
look up what package those .ko files are in? I've tried a few, but no luck,
ie. oss4-base linux-sound-base (already loaded), not even in
linux-backports-modules-alsa-2.6.35-22...

A ray of hope shines in a dark and dreary wilderness!

the world can be a dark place. after hours of playing around i typed

   modprobe snd-mixer-oss

in terminal ... and ... tadaa ... after starting gnomradio there is no
more error message. volume control in gnomeradio also works as expected.
now i typed

   echo snd-mixer-oss > /etc/modules

to solve this problem permanently.

Since I upgraded to 10.10, this bug ("Could not open /dev/mixer") affects me 
too. But after I click out of the error message, the sound gets through, 
although  cannot control its level with the gnomeradio sound level. I can only 
control the global system  sound (as usual).
My tuner card has an Audio Out jack which is connected to the Line In jack of 
my computer via an external minijack cable. Maybe this way of connecting it is 
the reason why I have sound, while the two other here do not. My tuner card is 
an old tuner card (2004 or 2005).

Me too.

Ubuntu 10.10 desktop i386 - Live CD

bt8x8 card

After start, gnomeradio puts up a dialog: Could not open "/dev/mixer"!
And then that is can not open /dev/radio (no wonder, that name is not used by 
kernel for ages...)

After I change the radio device to /dev/radio0 gnomeradio starts, and it
can fins stations, showing correct signal strengths. But nothing is
heard.

I tried playing with the gnome Sound Preferences settings, but no success.
Playing ogg music files from hard drive works fine.

Ask for any other information.
