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
