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
