Hi, After updating to kernel-2.6.11-1.1231_FC4 and kernel-2.6.11-1.1233_FC4 sound stopped working on my system. However, if I boot the 1226 kernel, sound works. I have a fully updated FC4test1 system for x86_64 and my soundcard is a Audigy 2 ZS (using the emu10k1 module). Do you know what I could do? Simon
