Hallo! I just registered to this mailing list because a developer kindly advised me to do so. I own the external sound card Audio Kontrol 1 from Native Instruments and I was happy to find that drivers for it are already in the making. I downloaded alsa-driver-1.0.14rc4 and compiled successfully with ./hgcompile, then I installed the module with: # install -m 644 snd-usb-caiaq.ko /lib/modules/`uname -r`/kernel/drivers/snd-usb-caiaq.ko # /sbin/depmod -a After the command: # modprobe snd-usb-caiaq I get the following error: FATAL: Error inserting snd_usb_caiaq (/lib/modules/2.6.20-15-lowlatency/kernel/drivers/snd-usb-caiaq.ko): Unknown symbol in module, or unknown parameter (see dmesg) dmesg shows the following: [10095.330000] snd_usb_caiaq: disagrees about version of symbol snd_pcm_new [10095.330000] snd_usb_caiaq: Unknown symbol snd_pcm_new [10095.330000] snd_usb_caiaq: disagrees about version of symbol snd_pcm_limit_hw_rates [10095.330000] snd_usb_caiaq: Unknown symbol snd_pcm_limit_hw_rates [10095.331000] snd_usb_caiaq: disagrees about version of symbol snd_pcm_lib_preallocate_pages_for_all [10095.331000] snd_usb_caiaq: Unknown symbol snd_pcm_lib_preallocate_pages_for_all [10095.331000] snd_usb_caiaq: Unknown symbol snd_hidden_kfree [10095.331000] snd_usb_caiaq: Unknown symbol snd_verbose_printk [10095.331000] snd_usb_caiaq: disagrees about version of symbol snd_pcm_lib_malloc_pages [10095.332000] snd_usb_caiaq: Unknown symbol snd_pcm_lib_malloc_pages [10095.332000] snd_usb_caiaq: disagrees about version of symbol snd_pcm_lib_ioctl [10095.332000] snd_usb_caiaq: Unknown symbol snd_pcm_lib_ioctl [10095.332000] snd_usb_caiaq: disagrees about version of symbol snd_pcm_lib_free_pages [10095.332000] snd_usb_caiaq: Unknown symbol snd_pcm_lib_free_pages [10095.332000] snd_usb_caiaq: disagrees about version of symbol snd_pcm_set_ops [10095.332000] snd_usb_caiaq: Unknown symbol snd_pcm_set_ops [10095.333000] snd_usb_caiaq: Unknown symbol snd_hidden_kmalloc [10095.333000] snd_usb_caiaq: disagrees about version of symbol snd_pcm_period_elapsed [10095.333000] snd_usb_caiaq: Unknown symbol snd_pcm_period_elapsed This may not look like much but it's the effort from a couple of days searching, reading and testing. I hope you can help me. -- Alex _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
