[alsa-devel] Issues with ATI IXP SB4x0

An Acer laptop with the ATI IXP SB4x0 chipset fails to detect the audio card. Here is the alsa-info file with latest Alsa, http://www.alsa-project.org/db/?f=b63339af32dd301eba9f5ef6a0787ccfbeb55778

What should be the next thing to try in order to solve this issue? The "Conexant ID 2c06" string in the file appears to refer to the modem (?). Googling with the subsystem ID '1025:009f only brings cases where the sound does not work. Any suggestions on where to look at?
