I run 'alsactl restore' on a machine with 2 sound cards -- a built-in 
Intel Corporation 82801EB/ER (ICH5/ICH5R) AC'97 Audio Controller (rev 
02) and a non-built-in Yamaha Corporation YMF-724F [DS-1 Audio 
Controller] (rev 03) -- and get the following message:

Unknown hardware: "YMF724F" "SigmaTel STAC9700,83,84" "AC97a:83847600"
"0x1073" "0x000d"
Hardware is initialized using a guess method

As a consequence the volume levels of the Yamaha card do not get 
restored to the levels stored in /etc/asound.state.  The volume levels 
of the built-in card however are properly restored.  The asound.state 
file has been created by executing 'alsactl store'.

The kernel has been built with support for ALSA.  I've built and
installed the kernel modules for both cards (not the ones in the 
alsa-driver package but those that come with kernel version 
Any ideas why alsactl cannot find the hardware it has previously 
identified as "YMF724F", "SigmaTel STAC9700,83,84", and so on?
