32 NOTES:
33 - Capture data is written unaligned starting from dma_base + 1 so I need to
34 disable mmap and to add a copy callback.
35 - After several cycle of the following:
36 while : ; do arecord -d1 -f cd -t raw | aplay -f cd ; done
37 a "playback write error (DMA or IRQ trouble?)" may happen.
38 This is due to playback interrupts not generated.
39 I suspect a timing issue.
40 - Sometimes the interrupt handler is invoked wrongly during playback.
41 This generates some harmless "Unexpected hw_pointer: wrong interrupt
42 acknowledge".
43 I've seen that using small period sizes.
44 Reproducible with:
45 mpg123 test.mp3 &
46 hdparm -t -T /dev/hda
