Michael Brown reports, "I figured it might be down to IRQ activity. It turned out to be xosview, which is a program to monitor system parameters, including IRQ. 'killall -STOP xosview' makes the noise reduce." ====== Any program which parses /proc can cause this, including ps and top. This is because current kernels do a great deal of blocking while handling the /proc filesystem. If you have a card which has tiny hardware FIFOs and requires constant low-latency access to the bus, the blocking by the kernel can cause problems. Buying a better sound card with better hardware, or avoiding /proc access will help. -Dan (goemon at anime dot net) ======
