I didn't say we have the same soundcard, I said we have the same chipset, but also that the same chipset can see different releases in time (my Macbook was bought in late 2008). Check your codec instead, by launching
cat /proc/asound/card0/codec#* | grep Codec
$ cat /proc/asound/card0/codec#* | grep Codec Codec: Realtek ALC269 Codec: Nvidia MCP79/7A HDMI Which, I think, means that MCP79 only controls HDMI audio output. I was looking at the wrong place all this time. This card is not shown when I run lspci. Anyway, I quickly searched the web and found nothing relevant but that: http://lists.alioth.debian.org/pipermail/debian-eeepc-devel/2010-February/00.... However, this error doesn't exist in the current kernel.
When you have the codec name, match it to a model parameter by checking the kernel docs at http://www.kernel.org/doc/Documentation/sound/alsa/HD-Audio-Models.txt
I'll try the parameters for ALC269. There are a few in that link, including two related to eeepc, and no parameters to MCP79.
