Based on the report of this service, certain actions should be taken.

The easiest option is the lack of sound due to the minimum volume installed on the device.

If the characteristics of the audio device allow you to use the sound set using a mixer to adjust the speaker volume or other devices, or programs separately. Also using a mixer is possible to adjust the sound balance, frequency (low and high).

And I have a problem in the other - the sound button hangs in the lower right corner and the window for adjusting is simply persistently not shown how much it is on the button. And if the sound is at the maximum, and on the street night? You will not prove the same neighbors that not your fault is that the button does not work, and therefore it is not possible to reduce the sound!
