Hi Pithball, Some progress again today ... I downloaded kernel source 2.6.18-rc3 this morning. It compiled and installed quite easily. I did not make much changes to 'make xconfig'. Only changed the processor type to 'Pentium M'. I booted the kernel, didn't spot any errors in fact. But ... still no sound :( The modules do get loaded ... # uname -a Linux localhost.localdomain 2.6.18-rc3 #1 Thu Aug 3 14:18:15 CEST 2006 i686 i686 i386 GNU/Linux [root@localhost ~]# lsmod |grep snd snd_hda_intel 18964 0 snd_hda_codec 150272 1 snd_hda_intel snd_seq_dummy 4484 0 snd_seq_oss 33024 0 snd_seq_midi_event 8192 1 snd_seq_oss snd_seq 51696 5 snd_seq_dummy,snd_seq_oss,snd_seq_midi_event snd_seq_device 8844 3 snd_seq_dummy,snd_seq_oss,snd_seq snd_pcm_oss 42752 0 snd_mixer_oss 17024 1 snd_pcm_oss snd_pcm 76676 3 snd_hda_intel,snd_hda_codec,snd_pcm_oss snd_timer 23428 2 snd_seq,snd_pcm snd 53124 9 snd_hda_intel,snd_hda_codec,snd_seq_oss,snd_seq,snd_seq_device,snd_pcm_oss,snd_mixer_oss,snd_pcm,snd_timer soundcore 10464 1 snd snd_page_alloc 10632 2 snd_hda_intel,snd_pcm Then I thought I also had to compile alsa sources again. I had to make a change to Makefile.conf, because I have modversions.h in .../include/config/modversion.h and not in .../include/linux/modversion.h as the Makefile was expecting. CFLAGS += -DMODVERSIONS -include $(CONFIG_SND_KERNELDIR)/include/config/modversions.h That KBUILD_BASENAME seems not to be defined. Although it occurs in some Makefiles.. Does it make sense I'm trying to compile alsa again? Or should it just work now? JeeBee.
