for application developers who want to use driver features with a
higher level API than direct interaction with the kernel drivers.
Unlike the kernel API which tries to reflect the capabilities of the
hardware directly, ALSA's user space library presents an abstraction
which is as similar as possible across disparate hardware. It does this
in part by using software plugins. For example, many modern soundcards
or built-in sound chips don't have a "master volume" control; for these
devices the user space library provides a software volume control
instead using the "softvol" plugin, and ordinary application software
needn't care about the difference.</i><br clear="all"><br>So, it seems that all alsa based drivers do have a Master mixer...<br><br>----<br>Fabio Pugliese Ornellas<br>E-Mail: <a href="mailto:fabio.ornellas@gmail.com">fabio.ornellas@gmail.com</a><br>

</div>So there is no way to set the channel apart from the kernel?<br>
I always thought that this might get setup also by parts of<br>
the hardware itself. If not fine, then let's change it :)<br>
