I can mitigate them somewhat by reducing the horizontal refresh, or fix it completely by going to a lower video mode. I don't consider it a big deal this being the low-end EPIA5000, though it is worth noting that the higher-end models, e.g. the EM6000 and the M9000, use much faster memory and probably don't have any issues in this regards. It's rather odd. Decreasing the vertical refresh rate makes the problem worse. Increasing it seems to make things better. Very odd. -Matt Matthew Dillon :Hmm. I wonder. Have you tried this, and does it help?: : :http://www.mini-itx.com/faq.asp#Linux1 : : 3.2. What should I do if I have poor quality sound (pops, clicks and :squeaks) - particularly when dragging or scrolling windows? : : This is caused by X writing blindly to the video card's instruction :queue without checking to see if the queue is full. This will lock the :PCI bus for about 40 - 50 audio cycles, causing pops, clicks and :squeaks. The via82cxxx_audio driver is still somewhat fragile, so it is :possible that some applications will fault ungracefully if the bus is :disrupted badly enough (e.g. with SDL applications). : : You can make X play nice with the PCI bus by adding Option "PciRetry" :"true" to the "Device" stanza. Nasty pops and glitches will go away, and :system stability will be much improved. : :Cheers, : :AS To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
