in-call volume setting odd behavior

Some inconsistent volume settings noticed by users:

I then lower it to volume level 1 and the phone goes mute- which it should only do at zero. But then when I increase the volume back to level 2 it's quieter than it was previously- I'd say a level 1 volume.

It seems that to get to level 1 you have to lower the volume to no sound and then go to level 2 and level 2 will now be what level 1 should be.

in call volume volume display is like +1 visual queue above actual setting, I.E. have 1 "click" of yellow in volume readout as if volume is lowest, but get no sound, have ot have on 2 clicks of volume (kinda annoying when you get those loud callers, go to turn phone vol way down.... end up turning earpeice speaker off.)

Here's a logcat of this problem (filtered with 'grep Audio', I have complete logcat too if needed). Apparently the indicator can only go as low as 1 click, not zero clicks, it's mute at that setting.

I will mention that for the past few days I've dropped back to Bumblebee ROM for battery life reasons. One thing I noticed is they don't have the incall volume control go all the way down to mute. It can be lowered to the first volume level but not completely off. I'm thinking this bug is inherent in the kernel or something because it's obvious that Froyo people have had to deal w/ workarounds. I'll call my gf & see what her stock OV does

That's not a kernel issue, and something that I changed recently (after the GPS stuff). 9bdcb9b.

The minimum volume level should be unrelated to the inconsistent real volume. If you look at the logcat output you can see the correlation between setVoiceVolume (input) and "setting in-call volume" (output - what's sent to the audio chipset via RPC).

If you look at the commit diffs I also changed the rounding algorithm, but I don't expect that to make much of a difference. I suspect the problem is either the auto volume control (change that file to contain a zero instead of a one) or a bug with the audio hardware.
