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 |
