Estou tentando fazer meu microfone interno funcionar. No pavucontrol, não vi nenhum dispositivo de entrada. [1] Mudei 'Áudio integrado' para 'Duplex estéreo analógico'. Depois disso, existe um dispositivo de entrada, mas informando que está desconectado. [2] Também tentei silenciar um dos canais sem sucesso. A captura no alsamixer está numerada. [3]. Posso conectar meu fone de ouvido sem fio como um microfone.
Aqui estão algumas saídas:
