Playing audio CDs with KSCD is fine. System sounds (KDE startup and shutdown) are heard (MIDI instruments may be wildly incorrect, but sounds will sometimes play). But sounds from the Net are not heard. (No, I have not tried Opera or other browsers yet).
My equipment is good quality and gently used:
Gigabyte 970A-UD3 motherboard, AMD Athlon 8150 8-core CPU, 16 GB Ram, NO overclocking
Gigabyte 6770 PCI-E passive-cooled video card (GIANT heatsink/fins)
Audigy2 ZS Gamer sound card (not used by Windows, IIRC)
Seasonic M12-II Bronze Evo Edition PSU (520W IIRC)
I think it's a 3 TB SATA drive. It's dual-booting Mageia 5 and Win 7 Professional (both 64-bit).
Here is the first command often asked for. I did not type the ASCII line-characters near PID 1895 and 1917:

The output of "pactl list cards" is far too long to hand-type, though I can use pastebin if needed. Basically, the output of this command names three sound cards - Card #0 is the ATI "Juniper" HDMI audio unit on the Radeon 6770. Card #1 is SBx00 "Azalia (Intel HDA)" which appears to be the sound chip on the motherboard. Card #2 is the SB Audigy 2 ZS.
The output of "getfacl /dev/snd/*" is likewise pretty long.
When I first started having problems, I removed my speakers from the IOGEAR KVM and plugged them directly into the motherboard sound output. I no longer have 2 computers at my desk - removing the KVM removes a possible point of failure. If I plug the speakers into "front speakers" plug on the Audigy 2 ZS, audio CDs are not heard. Clearly the motherboard audio's front speaker plug (with the "pale green" plastic around the plug) is where I should focus my efforts.
Are there any more commands I should run?
Does anyone know what might be going on? Any help is much appreciated, thanks in advance!
