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).
