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 | |
