Cooler Master MasterPulse Pro 7.1 Microfone USB muito silencioso Ubuntu 16.04

Question

Então eu só tenho esse fone de ouvido para jogos para minha máquina Linux e o microfone é muito silencioso. O volume do microfone está no máximo e pode ser ouvido no jogo se outro som do jogo não estiver muito alto, mas é muito silencioso.

A opção de ganho no painel de áudio está esmaecida.

Alguma ideia? Curto de mudar um driver, eu tentei tudo o que posso pensar.

Obrigado.

Answer 1

verifique as configurações de gravação do ALSA em - alsamixer - c 0 --view capture

pode ser um controle adicional para aumentar o nível do microfone em 10dB ou 20dB, além do controle de nível normal

recomende reduzir o nível antes de aumentar o aumento!

o comando amixer -c 0 exibirá as mesmas informações da ALSA em formato de texto.
comandos amixer usando a opção 'set' podem ser usados para alterar qualquer configuração

O aumento do nível de ALSA no microfone também deve aparecer no Pulseaudio
