The issues I am having are with a new mini-itx Gigabyte GA-HN55N-USB3 motherboard put in the loungeroom as the main mythtv box. This is connected via hdmi to a Panasonic Viera plasma TV. This mb is an intel based board with an Intel Core i3 series processor, and Realtek ALC892R codec, HD audio etc.
I am running mythtv-0.24-0.pm.6.2-X86_64 (binary packages from packman), one package Mythnetvision does have video but no audio when accessing youtube etc.
Similarly if I run Firefox and go to youtube, I have video and also no sound. (An element to using mythnetvision which is still in beta, is a working flash install which I do have). I do have full sound available for music, TV recordings, and videos, which is great.
I have been running opensuse 11.3 and do fairly regular updates, I have 3 other PC's based on Gigabyte motherboards with AMD Athlon(tm) 64 X2 Dual Core Processor 5200+ and Nvidia cards. On each of these I can run any of the multimedia applications, including mythtv, and Youtube on Firefox and sound is OK via the onboard soundcards using basic computer stereo speakers.
To test the mini-itx further I connected a standard pc screen, together with a pair of pc stereo speakers to the line out jack (green) I then got all sound I wanted, mythnetvision accessing youtube etc. as well as Youtube on Firefox.
I have read and tried a number of suggestions from the forums in adjusting the order of the playback settings in KDE Personal settins/computer administration/multimedia but have had no luck.
Here are the details:
OS opensuse 11.3 x86_64
KDE 4.4.4 (KDE 4.4.4) "release 3"
motherboard audio 1. Realtek ALC892 codec
2. High Definition Audio
4. Support for S/PDIF Out

I have checked sound card settings in Yast2 and can get no sound , with hdmi connected, can get sound when I used the line out and stereo speakers.
If I try to use kmix it generally crashes.
I hope this may give some of the kind people here enough info to advice me, if there is anything I have missed please ask.
