Microfone detectado, sem som.

Prazer pessoal.
Eu tenho ubuntu 24 e uma alc887. Saída funciona perfeitamente, microfone não. O microfone é detectado mas não sai som algum. Já tentei alterar os arquivos de configuração e não funcionou. Eu gravei arquivo e reproduzi, mas não saiu som algum. Tentei as soluções aqui do fórum, não funcionaram. Alguma dica? Obrigado.

Poderia dizer, se não for muito incômodo, qual a sua máquina (PC ou notebook), placa-mãe e processador e se o microfone é de plug (p2), usb ou BT?

Roda o alsamixer na linha de comando e veja se as saídas estão habilitadas e no volume adequado.

Sim, estão ativados e tenho instalado o EasyEffects. O programa detecta o microfone, as barras aparecem como se houvesse som, mas deve ser ruído de fundo, porém não há nenhum som e no pavucontrol a barra ficar variando.
