Well, I do have a P4, and had built everything with -march=pentium4. However, rebuilding the kernel and modules with -march=pentium3 produces the same results. Incidentally, my audio hardware is: pcm0: <Intel 82801CA (ICH3)> port 0xdc80-0xdcbf,0xd800-0xd8ff irq 11 at device 31.5 on pci0 pcm0: <Cirrus Logic CS4205 AC97 Codec> (Dell Inspiron 8200 laptop) -Jon On Tuesday 20 May 2003 11:30 am, Morten Rodal wrote: > On Tue, May 20, 2003 at 10:25:30AM -0400, Jon Lido wrote: > > Where I've noticed the problem is playing when lossy > > audio.
