desativa o áudio HDMI na placa gráfica radeon

1

Como posso desativar o áudio HDMI na minha placa gráfica radeon?

Eu tentei passar os parâmetros de inicialização do kernel, mas isso não ajudou:

radeon.audio=0
snd-hda-intel.enable=0,1 

Estou usando o kernel personalizado sem suporte a carregamento de módulos (todos os drivers estão diretamente no kernel). Eu suponho que preciso desativar o módulo na inicialização do kernel.

a seguir é relevante a oputput de lspci -v
