Sound card driver in use was intel 8x0 (but I doubt it's responsible in this case). ALSA ../alsa-kernel/core/pcm_lib.c:216: Unexpected hw_pointer value (stream = 0, delta: -255, max jitter = 256): wrong interrupt acknowledge? If I understand the relevant code correctly, then this error message is triggered unnecessarily if the hardware buffer is only two periods in size. It is triggered when the hardware pointer has already been increased by one sample since the last period completed. Not so if there are more periods per buffer.
