Поставил KDE, наблюдается то же самое. Излечилось так:
# pacman -S alsa-oss alsa-utils
# modprobe snd-pcm-oss
(или так: echo 'snd-pcm-oss' > /etc/modules-load.d/snd-pcm-oss.conf )
# systemctl enable alsa-store
# systemctl enable alsa-restore
Такая же проблема, но в XFCE и скорее всего связана с systemd.
Вот, что у меня:
# systemctl enable alsa-store
The unit files have no [Install] section.They are not meant to be enabled using systemctl.
# systemctl enable alsa-restore
The unit files have no [Install] section.They are not meant to be enabled using systemctl.

В вики написано:
Note: Если сервис-файлы не имеют раздела Install, это обычно означает, что данные сервисы вызываются автоматически другими сервисами. Но если вам требуется установить их вручную, используйте следующую команду, заменив foo именем вашего сервиса.

# ln -s /usr/lib/systemd/system/foo.service /etc/systemd/system/graphical.target.wants/
Так автоматически они вызываются? Или создать ссылки вручную надо, но куда ссылки?
Удалил пульс:

pacman -Qs pulse
local/libao 1.1.0-2
    Cross-platform audio output library and plugins
local/libcanberra-pulse 0.28-5
    PulseAudio plugin for libcanberra
local/libpulse 2.1-1
    A featureful, general-purpose sound server (client library)
local/pavucontrol 1.0-1
    A GTK volume control tool for PulseAudio

Теперь при входе в настройки громкости xfce4-mixer выдаёт ошибку:
“Не найдено ни одного звукового устройства поддерживаемого звуковой подсистемой GStreamer. Возможно, у вас отсутствуют необходимые для GStreamer пакеты или неверно настроены права на доступ к звуковому устройству. ”

Зато теперь в alsamixer defaul = CA0106

Но звука так и нету в XFCE!

Натсройки gstreamer:

Куда устройство делось?
Подождём….
Или это повод перейти-таки с gdm на lightdm хот бы…
nafanja
попробуй удалить
pulseaudio и pulseaudio-alsa
если не поможет будем думу думать

и у тебя ДЕ гном или xfce ?

спасибо, попробую. xfce у меня.

upd:

ну понеслась:
$ pacman -R pulseaudio pulseaudio-alsa
проверка зависимостей...
ошибка: не удалось подготовить запрос (не удалось удовлетворить зависимости)

это ж целый gdm выпилить надо :( нормальноработающей замены ему не нашёл…

Я бы первым делом посоветовал вообще избавиться от пулсаудио в системе (от него одни проблемы, хотя идея была отличная, но разработка не доведена до ума)
покажи
pacman -Qs pulse

Вроде прилез вместе с Gnome 3. Но это было давно - и работало с ним всё хорошо, даже когда гном снёс.

$ pacman -Qs pulse
local/libao 1.1.0-2

pavucontrol выводит только одно устройство Фиктивный вывод. Его ставил для того, чтобы можно было переключать каналы с 2 на 5.1
Там скорее всего решение в том, что стояло mute - автор не написал, в чём решение…
У меня же вместо MM стоят 00.
Почему по умолчанию стоит какая-то левая карта? Как поставить Ca0106? Или дело не в этом?
В gstreamer-properties стоит везде ALSA.

Установленная карта дефолтная:


Работающая ранее, как карта по-умолчанию:


xfce4-mixer:
Возникла та же проблема, видимо после какого-то обновления, потому что я ничего не нажимал в звуке давно.
Подскажите, решение. А то в названии “Решено”, а решения в теме не вижу…
Карта: Creative Audigy SE (CA0106)

В xfce4-mixer выбрана Звуковая карта “Playback: Фиктивный выход (PulseAudio Mixer)” пишет:

Не выбрано ни одного управляемого канала. Вы можете выбрать каналы с помощью диалога Выбора канала.

Выбираю там единственный канал Master.

Регулятор громкости движется? Но ничего же не происходит.
