Uh, I meant "no audible improvement". However I've just checked the DAC datasheet again and it requires 1ms delay between turning on/off the supply and switching /PD pin (connected to OMAP3_PANDORA_DAC_POWER_GPIO). Even though I hear no difference, adding the delays back just in case. Updated patch attached.
Which step of the powerup is the one that generates the pop? As Liam says if you can mute the DAC while powering up might help if that's possible, though looking I don't think it is.

Please don't append patches to messages like this, it makes them harder to apply since the e-mail text ends up as part of the commit message as does the patch header.
Applied, thanks.
