| 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
