> > I have an AMD system with Sabertooth 990FX motherboard, running Kubuntu 12.04 and KDE 4.11.1. Chipset is AMD990FX/SB950, and audio spec is Realtek ALC892 8-channel Hi Def audio. I have audio outputs connected to the analog out ports, and digital coax out to a mini-card connected to the SPDIF-Out connector on the motherboard. Output of lshw for multimedia is below. <a href="http://git.kernel.org/cgit/linux/kernel/git/tiwai/sound.git/commit/?id=9a08160bdbe3148a405f72798f76e2a5d30bd243">http://git.kernel.org/cgit/linux/kernel/git/tiwai/sound.git/commit/?id=9a08160bdbe3148a405f72798f76e2a5d30bd243</a> Have you turn on " IEC958 Default PCM" using alsamixer -c0 ? > > Audio configuration is thru System Settings -> Multimedia -> Audio and Video Settings and accordingly thru Phonon multimedia framework. I can get audio out either thru Analog Stereo jacks or Digital Coax (designated Digital Stereo IEC958) jack, but I can't get output thru both simultaneously, and I can't find anything in Audio and Video Settings to do so. It must be possible, as this is a Windows/Linux dual-boot system, and I get simultaneous audio output with Windows. > > Can someone tell me how to configure my Kubuntu system for simultaneous audio output? >
