Sound output on the PC is only connected via the HDMI cable to the TV, via the ATI graphics adapter.

SeaMonkey VLC Firefox

KMix on Kicker show a line through, as if muted, though volume level indicator is all the way up. Though now I'm all about getting things working as expected on one particular installation, the strike through on the KMix icon is a too common sight here.

Pavucontrol actively confirms system sounds not working, though others are, by window flashing like I've never seen. Its sound bars indicate activity when system sounds are expected, such as clicking the test button in KControl.

In KControl, all settings seem defaults for General and Hardware, Enabled on the General tab, and Autodetect on the Hardware tab's select list. The only box there checked is Full duplex. System Notifications appear all to be on their defaults.

All these packages are installed: # rpm -qa | egrep 'puls|alsa|pavu|sound|mix|audio|pavu' | sort alsa-1.1.5-lp152.9.4.1.x86_64 alsa-firmware-1.0.29-lp152.4.2.noarch alsa-plugins-1.1.5-lp152.4.1.x86_64 alsa-plugins-pulse-1.1.5-lp152.4.1.x86_64 alsa-utils-1.1.5-lp152.6.3.1.x86_64 audiofile-0.3.6-lp152.5.7.x86_64 libasound2-1.1.5-lp152.9.4.1.x86_64 libaudiofile1-0.3.6-lp152.5.7.x86_64 libgstaudio-1_0-0-1.16.2-lp152.2.16.x86_64 libpulse-mainloop-glib0-13.0-lp152.2.3.x86_64 libpulse0-13.0-lp152.2.3.x86_64 libwebrtc_audio_processing1-0.3-lp152.3.10.x86_64 pavucontrol-3.0-lp152.3.7.x86_64 pulseaudio-13.0-lp152.2.3.x86_64 pulseaudio-bash-completion-13.0-lp152.2.3.x86_64 pulseaudio-module-x11-13.0-lp152.2.3.x86_64 pulseaudio-system-wide-13.0-lp152.2.3.x86_64 pulseaudio-utils-13.0-lp152.2.3.x86_64 sound-theme-freedesktop-0.8-lp152.3.3.noarch trinity-kmix-14.0.9-1.oss152.x86_64 trinity-libarts-audiofile-14.0.9-1.oss152.x86_64 yast2-sound-4.2.4-lp152.1.8.x86_64

What does it take to enable system sounds in this situation? Is KMix getting in the way of something, or being lead astray by pavucontrol? Is there some other package that needs installing?
