Is there any sort of > hack I can put to check if that is the problem? The cache flush method is quite CPU specific, you have to check datasheet. But it's only guess and the problem might be somewhere else. I would compare samples DMA ring buffer in the user space and kernel space again. Also, put a debug lines to dmix plugin to detect where are samples written (to which pointer/area in the DMA ring buffer). dmix assumes that playback is running forever and tries to mix data in actual ring buffer position.
