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 |
