To the devs:
I chatted with the OP on IRC. The problem stems from the fact that his hw:0
is the HDMI audio output which has apparently no audio controls in alsamixer
(like "Master" channel, etc). His actual sound card is at hw:1.
Now, the mixer GUI allows one to select which sound hardware to control, but
that GUI is accessible only from the mixer icon on the shelf. Since the
mixer icon doesn't show up in the shelf, there is no way for the OP to
change this preference.
I could myself reproduce this behavior and I can see that if I switch the
settings in the mixer icon to the audio output from my nvidia graphics card
then the mixer icon just disappears. And there is no way of getting it back,
other than hacking into modules.mixer.cfg.
Possible remedy: perhaps the mixer should check whether the Master channel
or PCM channel is present in the current hardware device and if it is not
present, then it could perhaps go on to the next hardware device, or simply
show the mixer icon but refuse to control the hardware.

The demand for IT networking professionals continues to grow, and the
demand for specialized networking skills is growing even more rapidly.
