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 */ |
