SubjectSound problem with AC97 module
	  Hello!

I have a Dell precision 220 at work with an built-in sound card. The
problem I have is that I continiously get these error messages in my logs:

Dec 14 18:21:02 shookay kernel: DMA overrun on send
Dec 14 18:21:02 shookay kernel: i810_audio: drain_dac, dma timeout?

I have joined output of the module and output of lspci. My motherboard's
chipset is an i820.

If I can give further help or debugging stuff, please let me know!

Regards, Mathieu.

Here the output of the soundcard module:
