Describe the problem:
Volume control doesn't work. When I try to mute or adjust the volume with 
"m" and "[" or "]" I get the following error message in the console: 
"/dev/mixer: : No such file or directory".

Please provide any additional information below.
My sound card - "Intel 82891EB/ER (ICH5/ICH5R) AC'97 Audio Controller" - 
doesn't have a hardware mixer (no /dev/mixer or /dev/mixer0). When I start 
mupen64plus I get the above error message. When I try to adjust the sound I 
get the error message and it doesn't work.

The SDL audio plugin support 2 different methods of volume control.  You can 
edit the
mupen64plus configuration file to select the other method.  This file is 
located at
~/.config/mupen64plus/mupen64plus.cfg.  If you open this file in a text editor,
search for "VOLUME_CONTROL_TYPE".  Change the value from "2" to "1",

Config file didn't originally have [Audio-SDL] section in it. I don't know what 
I
did, but now it does, which contains VOLUME_CONTROL_TYPE configuration.
