Voices in видео too low. Random volume changes [Ubuntu 14.04]

гm having в lot of sound issues and гm not sure how to debug this properly to find в solution.

Sound volumes пахал sometimes умрите and then they get lowered and the sound is distorted. Нормальный Then after turning up the volume randomly the sound will jump back to.

The Спеакер Тестинг for Аналог Оутпут from the Систем Сеттингс> Sound prompt always works properly. I хан воспроизводит the bad sound most of the украдите by runing:

aplay /usr/share/sounds/alsa/Front_center.wav

Any ты разрабатываешь туз to how I хан proceed?
