[Olivier SCHMITT]

Hello dear dev team members,

I just try to compile all for my ubuntu 18.04 to run more than 32 loopback.

I have found something about to :

-compile kernel with kconfig CONFIG_SND_MAX_CARDS=256
-compile alsa-drivers, alsa-lib, alsa-utils with gitcompile 
--with-max-cards=256

but when i try to compile alsa-utils i get:

checking for dlopen in -ldl... yes
checking for ALSA LDFLAGS...  -lasound -lm -ldl -lpthread
checking required libasound headers version... 1.0.27
checking for libasound headers version >= 1.0.27 (1.0.27)... found.
checking for libatopology (sound headers version > 1.1.9)... yes
checking for snd_ctl_open in -lasound... yes
checking for snd_tplg_new in -latopology... no
configure: error: No linkable libatopology was found.

Can you help me? I dont found anything about this error on the web...
