Som chiando no ubuntu 12.04 64bits

[Kadu_tbj]

Ola amigos quanto tempo hein!!!

Bom tenho um notebook toshiba que vc pode ver a configuração ai na minha assinatura e som dele sempre foi baixo, nunca testei o som dele no rwindows pois assim que comprei instalei ubuntu. Hoje resolvi comprar umas mini caixas de som usb da marca delux

De cara fiz o teste e sai o som com uma chiadeira horrivel, dai fiz o teste na maquina virtual com win 7 deu no mesmo, imediatamente fiz o teste no not da minha esposa com win7 64bits, e som sai perfeito.

Então verifiquei 03 coisas:
01. Eu estava no meu not sem bateria, ligado direto na tomada. resultado: som chiando.
02. Notebook com bateria e com a fonte conectada. Resultado: som chiando.
03. Notebook com bateria e sem fonte conectada: som normal, lindo, perfeito e sem chiado.

Ja verifiquei as configurações de som e aparece: ¨usb spaker¨ analogico e digital (as duas servem mas ainda assim fica chiando). Ja atualizei o sistema com apt-get update e upgrade.

Alguma solução?
