Hi,

Do you know how much do these scenario's generally create power draw?
A. Amplified audio playback to headphones through 3,5mm port in N900 for example.
B. USB LPCM audio data output.

I'm interested in this since N9 might have USB host mode feature, which would open possibilities for USB audio output.

I'm wondering what kind of hit USB audio output might put on battery, if it's more or less than amplified line output to headphone port.
