I have an older desktop, which I built back in 2008. It was state of the art, at the time. Gigabyte EP45 motherboard with SATA 2.0 and first generation PCI Express with onboard support for Dolby Home Theater audio. I installed an Intel Quad-core 2.4 GHtz processor (overclocked to 2.8 GHtz) and an Nvidia Geforce 560 Graphica card. I still use this system today. The only problems I've had is fans needing replaced. As the title of this post says, I can no longer use my 5.1 Dolby Digital onboard sound, because now, the only audio choice is the HDMI output from my graphics card! I imagine the firmware team, or the kernel team, or whoever, is celebrating that they got what was required to enable that. I know about the past struggles with sound cards on Linux. I'm not exactly 'new to Linux'. As you can see from my profile, I am an old codger. And just by using the word 'codger', you should know. ;^> Anyway, I'm pissed they have now restricted my use of the builtin audio codec on my motherboard. And the attraction of Linux (Li-nuks as Linus pronounces it) has always been about supporting all hardware, old and new. Stay optimistic all.
