Estou configurando um pequeno computador Linux (C.H.I.P.) para ser um receptor bluetooth usando pulseaudio. O dispositivo é sem cabeça, então eu gostaria de obter uma configuração que funcione na inicialização. Tudo está bem, exceto quando meu telefone se conecta a C.H.I.P. algo sempre define seu volume de coletor como 0%.
Como faço para que o Pulse / ALSA deixe o volume principal sozinho quando o pulseaudio configura a entrada sink? Ou talvez o pulso seja o culpado - não tenho certeza.
module-*-restore do pulseaudio. alsactl store system.pa e / ou default.pa para fazer o pulseaudio definir o volume desse coletor para 100% Se eu estiver executando o alsamixer enquanto meu telefone se conecta, vejo o volume passar de 100% para 0% em torno da seguinte linha de registro:
D: [pulseaudio] protocol-native.c: Client amixer changes volume of sink alsa_output.platform-1c22c00.codec.analog-stereo.
Tudo o que tenho que fazer é executar o alsamixer e definir o volume do Master para 100%.
Aqui está a minha mensagem para pulseaudio-discuss (zero respostas a partir desta escrita).
