So I believe I have a Sigmatel chip. I cant find it in here when I input in kernel: lspci -v. I also checked the website: http://www.alsa-project.org/alsa-doc/ and could not find the sigmatel driver. Can anyone help. I'm a two-day old noob when it comes to linux. Any help would be appriciated. Thanks.
