I have recently moved my desktop system into a rack mount case and rearranged my office. There were a few changes I ended up making because the rack case I ordered is a little short on depth. I ended up replacing the Gigabyte ATX motherboard with Intel CPU to a mini-ITX board with an AMD CPU which fits better. I transferred the hard drives and everything was working just fine...except for sound.
I spent a good bit of time tracking this down. The audio devices were recognized, the sinks were all operational (I could see activity on the meter in the sound settings), but there was no actual audio through the TV which was my monitory. All this had worked with the same equipment under the Intel resgeme.
My searching online provided no real help. I had a friend from the Fedora IRC support channel check things for comparison. But we couldn't find any real differences after two days. Being still frustrated had me checking Google results again.
I had found this page and started to look it over this morning: https://bbs.archlinux.org/viewtopic.php?id=256989. It got me thinking about Alsa configurations which are part of an older configuration possibly left over from upgrades. I had my friend check his /etc/modprobe.d/alsa-base.conf for what he had. He didn't. Mine had some options.
