It's been many years since I've had any sound card problems, but yesterday I installed a second video card and now the sound is broken in a peculiar way. PulseAudio seems fine in that the PA Volume Meter shows that there is good sound levels from all the normal sources. From every direction, PA looks normal. I've checked the EQ and ALSA and my speakers and the ports, everything is right, just no audio signal coming out of the hardware.
I have been using the on-board sound card for a long time so I know it works in Linux. And, I know that the Radeon includes a sound card, so now I have three sound cards in the system, which is probably related to the problem, but I'm not sure how since it was working fine with two sound cards. If it was 1998, I would have thought it was an IRQ problem.
I suspect this is a known issue with a known solution, but I only find suggestions to disable sound drivers for the unnecessary hardware, but I cannot do that since they all use the same driver! Besides, that doesn't seem like the right solution since PA seems to handle multiple snd devices just fine.

My soundcard dsp0 with the speakers got replaced by the dsp on the video card which has no speakers on it. The video was set up (module loading) before the sound.
To check, something like 'aplay -l' lists them in order IIRC.
Solution, IIRC, was in /etc/modprobe.d
preinstall <video_module> <soundcard_Module>
choose the soundcard module with the most dependencies :-D.

That sounds pretty close, but I'm not sure it is quite the same. aplay -l lists the on-board card, the one I want to work, as the first card. So, I don't think loading the driver any earlier is going to help. Does that make sense?
The solution I offered still doesn't hurt, and just may fix it, if the order of alsa devices is somehow different to the OSS ones. There's also some snd-card0, & snd-card1 stuff you can put in modprobe.d to set things up. I'm noit sure if it's deprecated, but there may be a replacement. Google for it.

'preinstall' is not just deprecated, but obsoleted now; it produces an error. All is see now is 'softdep'. I will try to recreate your approach using this method.
I'm not entirely sure how to use 'softdep', but I put snd_hda_intel as a pre-dependency for fglrx and it didn't help. I even tried black-listing snd_hda_codec_hdmi and it didn't load, but my HDMI is still the only thing that works.
This is a strange one. So nobody is has seen anything like this before?
Well, you were right. Sounds is broken on matter what I do. I pulled the second card, putting the hardware situation back to the original state, but sound didn't return. I even tried and old kernel.
So, it was just coincidental that I when I added the video card, there was also an update to something--I'm assuming it was ASLA--that broke my sound card. F20 has been an horrible experience and it just keeps getting worse.
I put in a bug, so we'll see if someone at Fedora can help.
I have a love hate relationship with Fedora. I need it for the Electronic spin. I hate it's habit of updating to broken code. That's part of the package, but it's the part I don't want. This breaks with Fedora ethos, but if you get a set of bugs you can live with (which happens), I'd stop updating and only do so periodically.
Yeah, I was thinking about that, but it's a tenuous situation. Currently, I'm desperate for an update to fix several serious problems I'm having; so I'm inclined to update frequently. Then, even if you are satisfied, something serious, like a security update, could get released so you would be eager to update, then, too.
I don't understand this bit about updates breaking things. That's just not acceptable. I'm not running rawhide, but sometimes I think I might as well. Seems like more bugs get added to the stable release than fixes.
Fedora is free, and very up to date. The "price" is that it's a testing ground for RHEL. So their beta code (and sometimes it seems, their alpha code) goes into Fedora "updates" for testing.
The other thing that seems to go on is that when new versions are released, developers can backport some patches but not update the whole system.
I ended up in the other kind of mess. It had electronic programs that were a bitch to find, patch to work, & compile. All done for me in fedora - the only place they were done. Then they kept breaking the system with updates. So I updated every three months or so, and got work out in between. I wish that electronic spin had a sounder base.
If your system is broken, my non-kosher advice is keep updating until it's half right. Updates don't fix everything. Then be choosy what/when you update. The only issue needing attention recently was the heartbleed bug. Most of it you can ignore, usually. A piece pf software can be buggy as hell, but if it doesn't affect your system, who cares if you're a version behind?
I think you are exactly, right. I'm going to have to start vetting my updates. I already review the changelog for installed packages every week, but just for curiosity's sake; now, I'll have to really look for things I want/need. I normally update every weekend and have been doing that for so may years, now, it's just habit. The problem is, I've been waiting for some fixes for so long that I don't know how to get back to a satisfying state.
I started with Mandrake in the 90's and switch to Fedora for my home system when we started running RHEL at work. I don't remember having bugs added in between releases until about F15. That's when I started reporting more bugs, but even that doesn't seem to help.
