Codec sleep, saving power when idle

(1/2) > >>

dreamlayers:
On my 5G 30GB iPod, audiohw_close() (which puts the codec chip to sleep) saves about 7.5 mA.  More could probably be saved by shutting down some related hardware.  Of course, you can only do this when not playing or recording audio.  Is this a desirable feature?

If idle power consumption is reduced via this and other means, the end result could be similar to original firmware's sleep mode.  You could simply set an extremely long idle power-down time.

saratoga:
I think at very least it would be nice to have the codec off when music isn't playing, even if we don't have a proper sleep mode.

soap:
Desirable feature x10!

Chronon:
+1 for codec sleep!

Hillshum:
Do most targets have such hardware that could be shut off when unused?
