17 NOTES:
18 - Capture data is written unaligned starting from dma_base + 1 so I need to
19 disable mmap and to add a copy callback.
20 - After several cycle of the following:
21 while : ; do arecord -d1 -f cd -t raw | aplay -f cd ; done
22 a "playback write error (DMA or IRQ trouble?)" may happen.
23 This is due to playback interrupts not generated.
24 I suspect a timing issue.
25 - Sometimes the interrupt handler is invoked wrongly during playback.
26 This generates some harmless "Unexpected hw_pointer: wrong interrupt
27 acknowledge".
28 I've seen that using small period sizes.
29 Reproducible with:
30 mpg123 test.mp3 &
31 hdparm -t -T /dev/hda
