Instalei uma placa de som Asus Xonar DS 7.1 no HP Compaq Elite 8300 CMT . Funcionou bem até alguns dias, quando não há mais som. Eu tenho que selecionar manualmente a placa de som usando alsamixer . Depois de reiniciar tudo vai para o padrão e eu tenho que fazer isso de novo.
Eu instalei o controle de áudio por pulsos para selecionar a combinação certa para fazer o som funcionar. Às vezes funciona com saída analógica surround 5.1 + entrada estéreo analógica e às vezes funciona com saída analógica surround 7.1 + entrada estéreo analógica. A configuração tem que ser selecionada toda vez que eu escuto um novo mp3 ou até mesmo eu tenho que mudar o vídeo do youtube.
Li muito nos últimos dias. Eu tenho limpo instalado o Ubuntu 18.04. Tudo funcionou bem por alguns dias.
Por favor me ajude a configurar a placa de som Asus para ficar como padrão.
