When I playback audio I can hear the flickers dropping sound. Even without playback I can hear statics in my headphone every few seconds. Every time there is a flick, the icon with the speaker appears. When I run alsamixer I have the levels and set-up changing every few seconds. In the same time I have drops in the audio. Please look at the attached desktop video record. ALSA information is located at http://www.alsa- project.org/db/?f=5dc6ccc748f4331dcf4a8803235af60d9fbfadbc Don't hesitated to ask more info.
