| 32 | NOTES: |
| 33 | - Capture data is written unaligned starting from dma_base + 1 so I need to |
| 34 | disable mmap and to add a copy callback. |
| 35 | - After several cycle of the following: |
| 36 | while : ; do arecord -d1 -f cd -t raw | aplay -f cd ; done |
| 37 | a "playback write error (DMA or IRQ trouble?)" may happen. |
| 38 | This is due to playback interrupts not generated. |
| 39 | I suspect a timing issue. |
| 40 | - Sometimes the interrupt handler is invoked wrongly during playback. |
| 41 | This generates some harmless "Unexpected hw_pointer: wrong interrupt |
| 42 | acknowledge". |
| 43 | I've seen that using small period sizes. |
| 44 | Reproducible with: |
| 45 | mpg123 test.mp3 & |
| 46 | hdparm -t -T /dev/hda |
