Public bug reported:
After last update, I have lost the sound of my Asus Monitor which has
got speakers.
It is a problem with ALSA Audio because, the last update installed some
patch of ALSA.
Now, when I use for example VLC and try to change to my HDMI Audio
Controller, it works well, but If I do the same thing with a videogame
of Steam, like DOTA 2, I can't obtain the sound of the game in my Asus
Monitor.
I installed Pulse Audio to select the sound card which I want to use,
and when I try to change the sound card of the application DOTA 2, it is
impossible, I can't. I change it in the menu, but the option comes back
to USB Speakers.
Please solve it, I have lost my speakers with this update.
