Comprei o fone de ouvido recentemente e executei pactl list cards. Este é o meu resultado para o dongle USB relevante:

Este produto não é puramente plug-and-play. Para obter uma saída de áudio, tive que abrir as Configurações do sistema > Som e alterar manualmente a saída para o fone de ouvido Corsair. É uma solução simples, mas é algo que muitos podem ignorar.
