Hi,

I am trying out the latest snapshot of Alsa with Ubuntu 10.10.
It compiles without errors. However, when the modules are to be loaded,
there are Unknown symbol errors:

[ 332.243113] snd: Unknown symbol unregister_sound_special (err 0)
[ 332.243379] snd: Unknown symbol register_sound_special_device (err 0)
[ 332.245467] snd_timer: Unknown symbol snd_info_register (err 0)
[ 332.245631] snd_timer: Unknown symbol snd_info_create_module_entry (err 0)
[ 332.245839] snd_timer: Unknown symbol snd_info_free_entry (err 0)
[ 332.246210] snd_timer: Unknown symbol __snd_printk (err 0)
[ 332.246373] snd_timer: Unknown symbol snd_iprintf (err 0)
[ 332.246607] snd_timer: Unknown symbol snd_ecards_limit (err 0)
[ 332.246834] snd_timer: Unknown symbol snd_oss_info_register (err 0)
[ 332.246997] snd_timer: Unknown symbol snd_unregister_device (err 0)
[ 332.247224] snd_timer: Unknown symbol snd_device_new (err 0)
[ 332.247625] snd_timer: Unknown symbol snd_register_device_for_dev (err 0)

Is this a module loading order issue? Has there been a change in the
latest kernel
that causes the problem?
