Re: A quick spin vox-pop

[Bernardo Barros <bernardobarros@xxxxxxxxx>]

I don't know what I'm missing, but with my setup all applications that are not native jack clients (e.g. flashplugin etc) connect to jack automatically with the alsa-jack plugin. What feature pulseaudio is supposed to provide here?  It supposed to mix different clients in realtime or something fancy? In that case it does not make sense since it's not aware of the native jack clients.

One suggestion about the spin

Since it's KDE, there is no need to use pulseaudio. One elegant
alternative would be to exclude pulseaudio and include alsa-jack-plugin
providing a system wide alsa configuration (/etc/asound.conf) like this:

pcm.rawjack {
     type jack
     playback_ports {
         0 system:playback_1
         1 system:playback_2
     }
     capture_ports {
         0 system:capture_1
         1 system:capture_2
     }
}

pcm.jack {
     type plug
     slave { pcm "rawjack" }
     hint {
         description "JACK Audio Connection Kit"
     }
}

pcm.!default {
     type plug
     slave { pcm "rawjack" }
}

I would caution against removing pulse from the Spin. There's no need as long as we have and easy way to turn it off - either by using Jorns app or providing concise easy to access documentation on the wiki (there may be some overlap with the musicians guide here). Arch have been doing this really well for some time [1][2][3] and we could provide something similar.

Pulse achieves what it set out to really well I think but its domain is really not pro audio. Its a complicated beast and often where's the blame for bugs in ALSA and the kernel. An updated Common Pulseaduio troubleshooting wiki would be really useful here.

The pulse commit lists for some time now and they seem to be really active and very receptive to answering questions. We should start forwarding more bugs upstream. I'm watching the bugs as they come in and hopefully will have more time to act on them once F18 is released.
