Титла: Внезапно ми изчезнаха половината аудио канали в миксера
Публикувано от: ivanatora в Jan 02, 2014, 08:44
Здравейте, Този компютър не го бях ползвал 2 седмици и сега като сядам на него откривам че половината аудио канали ги няма в alsamixer и микрофона не работи. До сега беше на предния панел, работел е и на задните жакове. Започвам с дебъг инфото (системата е Ubuntu 12.04.3): $ amixer
