Re: [proaudio] netjack and several sound cards

Well I didn't try yet with jackdmp, so I can help you ... but you can ask to sletz on #lad IRC channel. He is the main developper.

Thanks. I use jackdmp and alsa_out is not on my system. But according to
http://www.nabble.com/NetJack2---development-status-(2)-td19168168.html and
http://trac.jackaudio.org/wiki/WalkThrough/User/NetJack2, "jack_load
audioadapter" can do the same.

The problem is that it just doesn't work. All that it make is a lot of

JackAudioDriver::ProcessAsync Process error
JackEngine::XRun: client = netmanager was not run: state = 1

And "jack_load netmanager" was running.

A side effect is that sound is not working afterwards (jackd is still
running, strange). I have to restart alsasound.

Cheers,
Dominique
