Subject: Re: RealTek Inverted Mic Patch

Hello,

   Thanks for applying it - there is one more piece of hardware that 
needs the same type of fix. Here's an updated patch...
just the addition of

SND_PCI_QUIRK(0x1025, 0x022f, "Acer Aspire One", ALC662_FIXUP_INV_DMIC),

over and above what was already in the last patch..
