Hi, I am having problems with my soundcard that I think might be fixable by increasing the buffersize, but the sysctl that reports the buffersize is readonly. Basically, even when there is relativly mild hard disk access (like a large cvsup) I start to get underruns (as reported by a verbose /dev/sndstat). CPU usage is nowhere near 100% yet the sound card is starved. I have tried tweaking everything possible in with my motherboard's BIOS with regards to PCI, AGP, and SDRAM read/writes to no avail. Any ideas? -Wade
