Add ASIO4All setup aid on first setup

[ann0see]

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)

This is already covered here: #710

@corrados I think you linked the wrong issue

[ann0see]

My proposal would be to check the ASIO driver name on Windows and show a message next to the ASIO setup Button which links to the wiki.
I can look into it.

[corrados]

You are right. This is the correct link: #129

@ann0see I like your idea. How hard would it be to indicate that there is no audio-in or audio-out configured?

[ann0see]

Unfortunately I don't know. How would you check if the wrong input/output was set up? We don't know which the right ones are.

I think the main mixer board should look different if you are not connected to a server.
My proposal looks ugly:

But something like that including a link to settings with has a small "play sound" button and a light indicating that the microphone detects something would be great.

I don't think only ASIO4All would profit from that.

Of course, we cannot know what is the right connection for the user. All we can tell the user is the connection is not defined (not connected to a device).

[ann0see]

I don't even think that we know that (since ASIO4ALL is automatically selected).

[ann0see]

I came up with another (probably bad) idea: We know that Jamulus needs exclusive access to the sound card. What if we start a program which wants to claim the soundcard (mic and output) and look for red crosses/yellow symbols? It could cause even more problems if the program accessing the soundcard doesn't give it back to jamulus but it might also help in short therm. I will look at it

[gene96817]

This seems to be a problem with Windows. This is primarily a problem if the user tries to use Jamulus with Zoom/Jitsi. Both programs can share the mic on a Mac. For Windows, the desired behavior is for Jamulus to keep the mic connection and let Zoom/Jitsi just have the video connection This suggests to me that the user just needs a warning that another application is attempting to access the mic. This doesn't solve the problem if Jamulus starts up after another app already has a connection to the mic.

[ann0see]

Yeah. I couldn't get the read cross again (started edge with Jitsi) so it's not really an option.

What I also experienced:

You must disable stereo mix to get correctly configured devices working.

Also there are a lot of problems with MS GS Wavetable Synth.

I don't think we should introduce another link to the Wiki in the GUI. We already have links in the Help menu (and if a user needs help, I hope he will look into that menu).

A better solution would be that Jamulus just runs correctly without having to setup anything (i.e. not using ASIO4All at all). A possible solution would be to use Portaudio. We already have an issue about this: #116

Portaudio can use Windows native audio interfaces so you do not need ASIO at all. Of course, it has to be evaluated what latency you will get by this but if you use your Laptop internal audio card with ASIO4All I assume the latency is not better than using Portaudio anyway.

BTW: The link in the Jamulus software Edit menu to the manual points to "https://github.com/corrados/jamulus/blob/master/src/res/homepage/manual.md". Havn't you moved that page? Should we update the link in the Jamulus software then?
