Olá [email protected]

Há mais de um mês tenho encontrado um problema para inicializar o sistema de som.
Acontece que toda vez que inicio o som fica mudo, tentando resolver troquei o pulseaudio pelo alsa, durante alguns dias funcionou e depois o alsa só inicializa no mudo.

Algumas informações

lspci | grep audio -i
00:1b.0 Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio Controller (rev 03)

Os modulos são carregados normalmente.

systemctl status alsa-state

Código: Selecionar todos: ● alsa-state.service - Manage Sound Card State (restore and store) Loaded: loaded (/usr/lib/systemd/system/alsa-state.service; static) Active: inactive (dead) start condition failed at Qua 2014-07-23 13:34:04 BRT; 1h 11min ago ConditionPathExists=/etc/alsa/state-daemon.conf was not met

Noto que /etc/alsa é uma pasta inexistente.

systemctl status alsa-restore.service

Código: Selecionar todos: ● alsa-restore.service - Restore Sound Card State Loaded: loaded (/usr/lib/systemd/system/alsa-restore.service; static) Active: inactive (dead) since Qua 2014-07-23 13:34:16 BRT; 1h 27min ago Process: 1258 ExecStart=/usr/bin/alsactl restore (code=exited, status=0/SUCCESS) Main PID: 1258 (code=exited, status=0/SUCCESS)

systemctl status alsa-store.service

Código: Selecionar todos: ● alsa-store.service - Store Sound Card State Loaded: loaded (/usr/lib/systemd/system/alsa-store.service; static) Active: inactive (dead)

Código: Selecionar todos: systemctl start alsa-store.service systemctl status alsa-store.service ● alsa-store.service - Store Sound Card State Loaded: loaded (/usr/lib/systemd/system/alsa-store.service; static) Active: inactive (dead) since Qua 2014-07-23 15:03:04 BRT; 2s ago Process: 2656 ExecStart=/usr/bin/alsactl store (code=exited, status=0/SUCCESS) Main PID: 2656 (code=exited, status=0/SUCCESS) Jul 23 15:03:04 manjaro systemd[1]: Starting Store Sound Card State... Jul 23 15:03:04 manjaro systemd[1]: Started Store Sound Card State.

Depois de inicializado não desmuta.

Código: Selecionar todos: amixer sset Master unmuted amixer Simple mixer control 'Master',0 Capabilities: pvolume pvolume-joined pswitch pswitch-joined Playback channels: Mono Limits: Playback 0 - 64 Mono: Playback 61 [95%] [-3.00dB] [on]

É só então com:

Código: Selecionar todos: alsactl init

Que o sistema de som inicializa, mesmo dando alsactl store, systemctl start alsa-store quando reinicializado o é preciso ir com alsactl init para o som funcionar.

De acordo com
https://wiki.archlinux.org/index.html/Al ... d.state.29

Criei a pasta /etc/alsa e o archivo vazio /etc/alsa/state-daemon.conf

Interessante é que no console o som está funcionando quando logo no xfce com mdm é que o som não funciona, então creio que possa ser alguma configuração do Xfce.

Além disso o pulse não funciona, mas gostaria primeiro de restaurar o alsa.

Olá danielbarsan, instala o pacote alsa-utils.

Código: Selecionar todos: sudo pacman -S alsa-utils alsa-lib

e para habilitá-lo no inicio da sessão digite:

Código: Selecionar todos: sudo systemctl enable alsa-store.service

Não Foi possível, retornou alguns avisos.

Código: Selecionar todos: sudo systemctl enable alsa-store.service The unit files have no [Install] section. They are not meant to be enabled using systemctl. Possible reasons for having this kind of units are: 1) A unit may be statically enabled by being symlinked from another unit's .wants/ or .requires/ directory. 2) A unit's purpose may be to act as a helper for some other unit which has a requirement dependency on it. 3) A unit may be started when needed via activation (socket, path, timer, D-Bus, udev, scripted systemctl call, ...).

Descobri outra coisa, se eu ligo o pc com os phones de ouvido, o som funciona, só quando não está plugado o fone que não funciona.

Comparei o amixer com ou sem o phone e o resultado é o mesmo

Código: Selecionar todos: amixer Simple mixer control 'Master',0 Capabilities: pvolume pvolume-joined pswitch pswitch-joined Playback channels: Mono Limits: Playback 0 - 64 Mono: Playback 64 [100%] [0.00dB] [on] Simple mixer control 'Headphone',0 Capabilities: pvolume pswitch Playback channels: Front Left - Front Right Limits: Playback 0 - 64 Mono: Front Left: Playback 64 [100%] [0.00dB] [on] Front Right: Playback 64 [100%] [0.00dB] [on] Simple mixer control 'Speaker',0 Capabilities: pvolume pswitch Playback channels: Front Left - Front Right Limits: Playback 0 - 64 Mono: Front Left: Playback 0 [0%] [-64.00dB] [on] Front Right: Playback 0 [0%] [-64.00dB] [on] Simple mixer control 'PCM',0 Capabilities: pvolume Playback channels: Front Left - Front Right Limits: Playback 0 - 255 Mono: Front Left: Playback 255 [100%] [0.00dB] Front Right: Playback 255 [100%] [0.00dB] Simple mixer control 'Mic',0 Capabilities: pvolume pswitch Playback channels: Front Left - Front Right Limits: Playback 0 - 31 Mono: Front Left: Playback 0 [0%] [-34.50dB] [off] Front Right: Playback 0 [0%] [-34.50dB] [off] Simple mixer control 'Mic Boost',0 Capabilities: volume Playback channels: Front Left - Front Right Capture channels: Front Left - Front Right Limits: 0 - 3 Front Left: 0 [0%] [0.00dB] Front Right: 0 [0%] [0.00dB] Simple mixer control 'IEC958',0 Capabilities: pswitch pswitch-joined Playback channels: Mono Mono: Playback [off] Simple mixer control 'Beep',0 Capabilities: pvolume pswitch Playback channels: Front Left - Front Right Limits: Playback 0 - 31 Mono: Front Left: Playback 0 [0%] [-34.50dB] [off] Front Right: Playback 0 [0%] [-34.50dB] [off] Simple mixer control 'Capture',0 Capabilities: cvolume cswitch Capture channels: Front Left - Front Right Limits: Capture 0 - 31 Front Left: Capture 17 [55%] [12.00dB] [on] Front Right: Capture 17 [55%] [12.00dB] [on] Simple mixer control 'Auto-Mute Mode',0 Capabilities: enum Items: 'Disabled' 'Enabled' Item0: 'Enabled' Simple mixer control 'Caller ID',0 Capabilities: pswitch pswitch-joined Playback channels: Mono Mono: Playback [off] Simple mixer control 'Digital',0 Capabilities: cvolume Capture channels: Front Left - Front Right Limits: Capture 0 - 120 Front Left: Capture 120 [100%] [30.00dB] Front Right: Capture 120 [100%] [30.00dB] Simple mixer control 'Internal Mic',0 Capabilities: pvolume pswitch Playback channels: Front Left - Front Right Limits: Playback 0 - 31 Mono: Front Left: Playback 0 [0%] [-34.50dB] [off] Front Right: Playback 0 [0%] [-34.50dB] [off] Simple mixer control 'Internal Mic Boost',0 Capabilities: volume Playback channels: Front Left - Front Right Capture channels: Front Left - Front Right Limits: 0 - 3 Front Left: 0 [0%] [0.00dB] Front Right: 0 [0%] [0.00dB] Simple mixer control 'Off-hook',0 Capabilities: pswitch pswitch-joined Playback channels: Mono Mono: Playback [off]

Acredito que o problema esteja no speaker

Código: Selecionar todos: Simple mixer control 'Speaker',0 Capabilities: pvolume pswitch Playback channels: Front Left - Front Right Limits: Playback 0 - 64 Mono: Front Left: Playback 0 [0%] [-64.00dB] [on] Front Right: Playback 0 [0%] [-64.00dB] [on]

Quando vou no alsamixer ele está zerado, mas como fixar nele um valor tipo 85%?

##SOLUÇÃO##

Encontrei no artigo https://bbs.archlinux.org/viewtopic.php ... 7#p1408627
No arquivo /etc/pulse/default.pa remover ou comentar a linha "load-module module-device-restore"

Após os reinicio funcionou
