Hi and morning Right then with a bit of help most things so far have been solved heres another one , Audio for the mst works well using PA apart from 2 glitches 1 : no audio from firefox on most sites or absolute full volume with no control over it at all ie no sound from youtube but if i download the video it is ok or go to another site try "quinton-mc.org.uk/vindex.html" just a few car club bits on a test / Play ground HTML5 page tey are all full volume and that is a lot when it comes on 4x140 watt . 2: I have an Nvidia graphics card GT220 that has HDMI output on it (i dont use it dont have anything to take HDMI in) but it keeps getting setup as the primary audio system there is an on board sound card as well that is disabled (really bad quality) i use an external USB sound card works well for the GBP 19.00 that it cost Certain games refuse point blank to use the external sound and insist on the HDMI job how can i stop this the HDMI is turned off every where i can find it what else do i need to do to remove it from being detected Pete . -- Powered by Kernel: 3.1.9-2-ARCH KDE Development Platform: 4.7.4 (4.7.4) 08:41:53 up 10:49, 5 users, load average: 0.01, 0.04, 0.05
