+ Some common info callbacks are prepared for easy use:
+ <function>snd_ctl_boolean_mono_info()</function> and
+ <function>snd_ctl_boolean_stereo_info()</function>.
+ Obviously, the former is an info callback for a mono channel
+ boolean item, just like <function>snd_myctl_mono_info</function>
+ above, and the latter is for a stereo channel boolean item.
