After further testing I found that the lack of sound on the headphone out occured on my system only with rdt kernels from PlanetCCRMA (go figure). Other Planet kernels. including kernel-2.6.10-2.1.ll.rhfc3.ccrma work perfectly with the new driver. I will investigate the cause, but wanted users watching this thread and planning an upgrade not to hesitate. The recent patches to hdsp.c are a godsend, thanks again, Thomas.
