[MMIXER]
- Rewrite topology node enumeration algorithm - Old algorithm didnt properly take in account sum/mux nodes, may assign nodes to multiple lines and was not able to detect circuits which may lead to infinite loops - New algorithm properly partitions the nodes and also checks if nodes has already been assigned. As a plus, it is also faster - Algorithm based on msdn http://msdn.microsoft.com/en-us/library/ff538873(v=VS.85).aspx - Tested on VBox 3.28 (AC97) - Please retest supported soundcards for regressions svn path=/trunk/; revision=49150
