Olá, recebi do meu emprego um notebook Acer Aspire F15 com dual boot (Win 10 + Ubuntu 14.04.5 LTS) e percebi que não há saída de áudio tanto no alto-falantes, quanto no fone de ouvido. Verificando o alsamixer, informa que está tudo perfeito e no Win 10 o audio funciona normalmente.00:00.0 Host bridge: Intel Corporation Device 5904 (rev 02)
