Well, as I said earlier: "Preferably, ALSA should work fine with both bluetooth headphones and the standard speaker. But as ALSA is unusable for standard speakers at the moment anyway, I don't mind tweaking and using it for bluetooth only first."
I have discovered significant, severe distortion when playing back audio on N810. At first i thought it was hardware (amp, speakers) however when i installed a newer esd client, the startup sound (synthesized) was loud and CLEAR.

In my tests so far, the worst distortion has occurred with mp3s through dspsink. Also mediaplayer is reducing volume by some 12dB compared to mplayer/xmms. Xmms so far seems to have least sound problems.

The audio problems sound a bit like digital distortion introduced somewhere. Also there is significant resampling degradation between 44khz and 48khz samples (.wav).

It's clearly a software issue, and one that must be resolved.
