Follow up #598 (comment) (this idea will not solve the problem but rather mitigate it)

It would be great to add a link to the ASIO4All setup on the new homepage if ASIO4All was detected on the first start of Jamulus/if Jamulus detects that something is wrong to facilitate the setup of ASIO4All.

Furthermore I experienced a hang on "Trying to connect..." if the soundcard was wrongly setup.

(For me the Trying to connect... message is too general at the moment, but that's another issue)
