I'm really sorry if this is the wrong place to ask or if this question was already answered 100 times before but I did not find anything about this. I'm running Fedora9 on an PS3. I configured pulseaudio and with the default kernel sound is running fine. Now I want to compile my own kernel. So I download the newest kernel sources from the ps3 kernel tree and created an config file with make ps3_defconfig. Well with this kernel sound aplay is working so sound support seems to be ok. The problem is that it looks like pulse audio is not finding the sound device. The mixer applet in gnome stop working too. So my question is what have to be activated in the kernelconfig, so that pulseaudio (or maybe audio, I'm not really sure if this is an pulseaudio problem) is working again. Maybe it has something to do with HAL support but I know really nothing about that stuff so I hope some "sound experts" could give me an Hand. Well since I'm nearly clueless when it comes to kernel debugging some may ask why I was trying. Well the reason is simple. The default kernel works but is really lame on an PS3 the kernel made with "make ps3_defconfig" is much faster but lacks sound support as described (and graphic support if you don't activate PCI support in the kernel config<-bug in xorg) Michael
