Eu comprei um microfone USB da Audio Technica há algum tempo, mas meu sistema não reconhece a entrada nele.
Quando eu o conecto e abro o Audacity, vejo as opções de entrada do microfone (como ' ATR USB Microfone: áudio USB (h: 1,0): Line: 1' ). No entanto, sempre que tento gravar qualquer coisa, acabo apenas com uma linha plana (indicando que não há entrada).
arecord -L dá isto:

Eu não tenho ideia do que qualquer um dos meios acima, mas me disseram que dar essa saída ajudaria.
Alguém tem alguma sugestão do que fazer nesta situação? Se houver algo mais sobre o qual eu possa elaborar, por favor, me diga e eu ficarei feliz em explicar melhor.
Obrigado antecipadamente!
EDIT: Aqui está o que eu tenho quando eu introduzi amixer no terminal:
