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.
