How many mixers normally should be in Fedora 20 kmix?

How many mixers normally should be in Fedora 20 kmix?
I play audio but don't hear anything.

I have noticed that I have 2-3 mixers on Kmix, however there was 6 mixers on Kmix mixers list.
Where does other mixers go?

Also, the F11 (mute sound) is appeared to be red. And it always red (should be white).

It depends on your sound card; but, should be the same number as the total of your audio jacks.
What is the sound card and/or the make and model of the PC if its a normal HP, Compaq, Dell, etc.

Having single pair mixers each with one channel called "Builtin analog audio" means you have pulseaudio installed (which is default configuration)
Do you see same problems with alsamixer(command line mixer)?

Ok, this problem is cured with
chmod o+rwx -R /dev/snd

Open in new window

But the problem appears at every startup.

You need to add user to "audio" group (default user created by anaconda is not there)

there is no such group.
[root@localhost nn]# cat /etc/group | grep audio
[root@localhost nn]#

I have tried
[root@localhost dev]# groupadd audio
[root@localhost dev]# useradd -g audio audio
[root@localhost dev]# chown audio:audio snd -R
rebooting...
