I've searched the local fs for the alsa-info.sh script as well as 
looking through the package contents on debian.org without any results.  
Where would I get this script from?  The kernel running on the custom 
distro is 2.6.33.3 with an alsa version of 1.0.23.  Also, I didn't 
compile or install the alsa-driver package, but it appears that the 
drivers are getting loaded for the hardware under the custom distro.

Per the instructions above, I have performed the alsactl command on the 
working system (Kubuntu) and the custom distro.  There are differences 
in the files which I've attached to this message.  Something else I 
noticed while in the alsamixer for both systems is that there are 
additional settings on the Kubuntu system as shown below.

Custom Distro:
Master, Headphone, Front, Front Mic Jack, Surround, Center, LFE, Side, 
Mic jack Mode, S/PDIF, S/PDIF Default, S/PDIF Playback, S/PDIF Playback, 
S/PDIF 1, Swap Center

Kubuntu:
Master, Headphone, PCM, Front, Front Mic Jack, Surround, Center, LFE, 
Side, Mic jack Mode, S/PDIF, S/PDIF Default, S/PDIF Playback, S/PDIF 
Playback, S/PDIF 1, Beep, Swap Center


Any ideas or other information required to help resolve this problem?

Thanks,
Dave
