i810_audio.c: Clicks while playing audio

Hi,

On a HP Vectra VL 400 with a i815 motherboard playing a .wav file (haven't
tried anything else) causes the sound to be played with a lot of periodic
clicks.
The kernel is 2.4.3
dmesg shows:
Intel 810 + AC97 Audio, version 0.01, 17:25:00 Apr 6 2001
PCI: Enabling device 00:1f.5 (0000 -> 0001)
PCI: Found IRQ 9 for device 00:1f.5
PCI: The same IRQ used for device 00:1f.3
PCI: Setting latency timer of device 00:1f.5 to 64
i810: Intel ICH 82801AA found at IO 0x1300 and 0x1200, IRQ 9
ac97_codec: AC97 Audio codec, id: 0x4352:0x5934 (Cirrus Logic CS4299)
i810_audio: 9568 bytes in 50 milliseconds
i810_audio: DMA overrun on send
i810_audio: DMA overrun on send

lsmod show:
root@darkstar:~# lsmod
Module Size Used by
i810_audio 14084 0
ac97_codec 7908 0 [i810_audio]

My question is: What does "DMA overrun on send" mean?

Regards,
Naren
