I'm thinking about buying wireless desktop speakers for ease of use with different audio sources (Notebooks, Mobile Phone etc.). For higher audio quality over the standard A2DP protocol there are different codecs needed unlike the mandatory SBC codec, which has a rather poor quality and high latency.
So I would like to know, which Bluetooth stacks ( Windows 7 built in and others) support which Codecs ( apt-x, AAC ), because I would like to use the internal Bluetooth hardware and not buying simply an apt-x enabled BT dongle for ease of use.
Does there a list exists, where I can get an overview about the supported codecs ? A big plus would also be a list , which mobile phones support these codecs in their bluetooth implementation.
