As a subsidiary question, what is the major difference between a warm
(reboot) boot and a cold (shutdown + power up) in term of power states? In my
case my device works fine after a cold boot OR after a wakup from sleep, but
it's silent after a plain 'restart'. The card appears to be in perfect state
as far as the controler goes, the DMA works, all is fine save there is no
sound.
That seems perfectly illogical to me, really ;-)
Any idea?
