Eu tenho o Linux Mint e o Windows 8 configurados para inicialização dupla. O hardware é um HP Spectre x360. Depois de usar o Windows e voltar ao Linux (seja por reinicialização ou após um desligamento completo), o áudio não funciona.
Se eu reiniciar uma segunda vez e inicializar de volta na partição Linux, o áudio começará a funcionar novamente. O áudio sempre funciona no Windows.
Eu tentei desativar a inicialização rápida do Windows, mas não faz diferença. Recarregando alsa também não tem efeito.
Quando em um estado não funcional, meu dispositivo de áudio não é detectado / listado por nenhuma das ferramentas alsa / pulseaudio.
Isso parece ser 100% repetitivo.
Quando não está funcionando:
