Не может играть звук, ошибки lib ALSA
EDIT Добавленный ls-l/dev/snd/
EDIT Добавленный amixer-c 0
Я пытаюсь заставить свой сервер человечности 12.04 lts играть звуковой файл. Однако я всегда получаю следующую ошибку, показываю от команды теста динамика.
ОБНОВИТЕ я больше не получаю следующую ошибку, звуковые файлы будут играть (должен был добавить мой пользователь к звуковой группе), однако никакой звук нельзя услышать.

Решено добавлением моего пользователя в звуковую группу.
sudo useradd -G sound {username}
Затем заставил мою интегрированную звуковую карту иметь индекс 1, поэтому по умолчанию для карты pci было 0.
Найдите карту, которую вы не хотите считать глухой. Мой snd_intel8x0. Текущее значение по умолчанию имеет индекс 0.
cat /proc/asound/modules
0 snd_cmipci
1 snd_intel8x0
Измените файл conf так, чтобы карта, которую вы не хотите использовать по умолчанию, была установлена на индекс 1
sudo nano /etc/modprobe.d/alsa-base.conf
Найдите строку:
# Prevent abnormal drivers from grabbing index 0
и добавьте следуя за ним, используя имя вашей звуковой карты вместо моего snd_intel8x0
options snd_intel8x0 index=1
Наконец перезагрузитесь и используйте alsamixer, чтобы убедиться, что карта не отключена.

Мастер-моно и объемный звук отключены. Если вы переключаете их, все должно работать нормально:
amixer -c 0 sset 'Master Mono' toggle
amixer -c 0 sset 'Master Surround' toggle
Если вы хотите изменить off на on, просто повторите те же команды, используя имя устройства.
Для изменения громкости следует использовать:
amixer -c 0 sset 'Master Mono' 100%
amixer -c 0 sset 'Master Surround' 100%
