feedback: Apple Tumbler and Snapper audio: looking for testers

[Andreas Tobler]

Hi Marco,

took a while, but finally I managed to test your patch on my AluBook.

It seems to work. I can hear a very quite output either on built-in 
speaker or on headphones.

I've done this on yesterdays src tree. Including my speed hacks.

The messages from the kernel:

pcm0: <i2s> mem 0x10000-0x10fff,0x8000-0x80ff,0x8100-0x81ff irq

enabled outputs: SPEAKER

cat /dev/sndstat

Installed devices:
pcm0: <i2s> at i2s [GIANT] (1p:1v/0r:0v channels default)

Unfortunately I do not seem to be able to use the mixer correctly. mixer 
doesn't report a default device. So I can't set the volume.

May I workaround this with setting hint.pcm.0.vol="50" in 
/boot/device.hints? I'll try.

Thanks,
Andreas
