I tried that now but I still can't play anything using alsa (or
anything else I've tried). Note that this is not just after reboot, I
also don't have working audio after a cold boot. Looking at the kernel
output from boot it looks like the driver load just fine, and I have
the device under /dev/snd/pcmC0D0p and it's listed using aplay -L:


Has anyone been able to test using a sabrelite or nitrogen6x to see if
they get the same result? I just use aplay to play a test file from
alsa (/usr/share/sounds/alsa/Front_Left.wav on most linux systems).
