как знать то, что является названием звуковой карты для увеличения уровня громкости

У меня есть linux2.6.38, и я не знаю то, что является моим названием аудиодрайвера для изменения уровня звука. Когда я пишу:

[root@FriendlyARM/] # amixer-D импульс sset Основное 50%-е управление c:902 lib ALSA: (snd_ctl_open_noupdate) Недопустимый импульс CTL amixer: ошибка импульса присоединения Микшера: Никакой такой файл или каталог

У меня есть встроенное устройство дружественной руки с Linux os.and, это - детали amixer:
