Lowering the Master volume to minimum turns off speaker output

Scenario:

Lower Master volume down to minimum. Raise it again to anything above min.

Expected results: Sound plays through speakers at desired volume.

Actual results: Speaker output has been disabled, causing no sound output.

Any ideas? My environment is XFCE4

Switches (speaker tickbox gets unchecked when volume is lowered to none, have to manually tick it again to get sound after raising volume)

0. Please turn your images into links or at least small thumbnails.
1. How do you lower the volume? Please use alsamixer from the command line and see if it also turns off the devices. Return with results.

Re: Lowering the Master volume to minimum turns off speaker output

I'm using the XFCE4 audio mixer app. If I use alsamixer, lowering the Master volume to 0 does not disable the speaker output. However, muting it does, and unmuting doesn't restore the speaker output.

So 2 things:

1) Using the XFCE4 audio app to lower the Master volume to 0 of the sound card (not pulse audio) actually mutes the Master volume. Muting the master volume has the effect of disabling the speaker output switch.

2) Unmuting the Master doesn't restore the speaker output, you have to enable it manually. This hpapens both in alsa-utils and  the XFCE4 mixer app.

It's probably a XFCE4 mixer bug. The mixer isn't being maintained upstream anymore. The xfce wiki article has more information and a link to a news item explaining why.
