From c032639678c494710f685612acffeae9b0f603f3 Mon Sep 17 00:00:00 2001 From: Mark Farrugia Date: Thu, 20 Sep 2018 17:23:42 +1000 Subject: Create avirt_stream structure in place of old config structures Remove unnecessary extra memory allocation with the old config structures. We can store the snd_pcm pointer, which contains lots of info already.
