Alsa sound playback failure in 2.6.0-test7

Alsa sound playback failure in 2.6.0-test7

[Rob Browning]

(Please CC me in any replies.)

This issue looks similar to a report posted earlier by someone using a
previous 2.6.0 test kernel.

Trying to run saytime on an Asus A7V600 (Via KT600 based) motherboard
using the onboard VIA audio (AD1980) produces no sound and the console
output included below.  The kernel was compiled with Debian's gcc-3.3
package, version 1:3.3.2-0pre4, and the machine has 512MB of RAM, no
swap, and had at least a couple of hundred MB free when saytime was
run.  Please let me know if I can provide any further information:
