Ah I see, so the automatic format conversion of ALSA does work for you, however dmix just causes dropouts with your low latency settings. Interesting that dmix does that, because usually the conversion is rather cheap. I wonder if its really dmix being the problem. Maybe you are already very close to the edge with your latency setting and current OS configuration and dmix is just the last tip on the scales to trigger the droput. And with your 32 bit patch you are always running rock solid 1ms latency without any drop outs ever?
