Проблема с работой микрофона в ОС Fedora

17.11.2013 20:39 #349842

В ОС Fedora на одном компьютере микрофон Genius MIC-01A после подключения и настройки заработал практически сразу, а на втором - не подаёт никаких признаков жизни. Может быть, причина в неисправной звуковой карте, но как это проверить? Заранее благодарен за любой совет по данному вопросу.
