Eu exibo meus computadores via HDMI em um receptor AV que vai para a tela.
Tenho notado que, se o receptor AV não estiver selecionado para o canal de computadores ao inicializar o computador, o Ubuntu não tentará direcionar o som pela porta HDMI e as opções HDMI não estarão disponíveis no menu de som. .
Alguém sabe de uma maneira de fazer com que o Ubuntu veja a opção de som se não estiver disponível inicialmente? No momento eu tenho que reiniciar
Saída do lsmod quando não consigo reproduzir som através do meu receptor AV.
