Comment 6 for bug 462654

I don't agree with you all. Option model=acer-aspire-4930g is good. The only thing that doesn't work is muting subwoofer which i fixed already. I will post fix officially when I clone alsa-kernel repository.

Note that after setting option to acer-aspire-6530g you won't be able to get sliders for 5.1 speakers and microphone doesn't work.
