[SOLVED] Broken Audio System

[Yoru3]

Thanks for the input Jerry.

I initially had started following this link, since it explained the problem,
http://bernaerts.dyndns.org/linux/74-ubu...lna-client
but the links and info appeared to be unreliable.

I also initially thought the link you provided was not relavent, because the list of plugins did not include the all important grilo Upnp/DLNA  client (renderer and controller) plugin.
To my mind this is an essential prerequisite of a good music player, since it allows effort to be focused on maintaining the quality of the one central store all of which is made available to all networked devices, (PC, tablet, digital radio, phone etc.) rather than a just a hodge podge of local files on each device.

But then I found another link, which not only highlights the issue, but gives a full solution that includes the grilo plugin. Again it's fossfreedom.

It sounded very possitive, so I thought I'd just follow the instructions.
However, I had also by this time installed another rhthmbox PPA (the webupd8team), so I first unticked it's box in the 'Software & Upates, Other Software' to prevent ambiguity.

Just for good measure I did the following, to prove the package could not be seen.
sudo apt-get install ppa-purge
sudo ppa-purge ppa:webupd8team/rhythmbox

Then I did
sudo add-apt-repository ppa:fossfreedom/rhythmbox
sudo apt-get update
sudo apt-get install rhythmbox
sudo apt-get dist-upgrade
sudo apt-get install grilo-plugins-0.2 grilo-plugins-0.2-mediascanner

After ticking the 'Tools, Plugins' box for grilo, the result was a fully working Rhythmbox v 3.1 app, which seems to be quite robust,
with a very large music library.

Only thing to fix now is the system sound, which I seem to have lost along the way earlier.
This was still working when the music sound was broken, so I guess it's based on a different system.
