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