</div>Hardware mixer controls != playback controls !!!<br>
<br>
Alsamixer accesses the hardware mixer of the soundcards/-devices. And most<br>
USB-devices don't have a hardware mixer. At least it is not accessible via<br>
software, just via the "hands on" hardware access :-) </blockquote><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">Which is actually a good thing because its one place less where the volume set<br>
to zero/mute gives you endless fights of getting sound of the speakers...<br>

Have fun,<br>

I just gave up because it wasn't my intention to make it do anything, just curious to see how it worked.</div>
