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.

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?

Thx, Gus

Based on your descriptions, I suspect this will probably need some manual tweaking within Pulseaudio to utilise both output connectors. Adding another profile to output to both simultaneously should suffice I imagine.

Unfortunately i'm not familiar with such arrangements with Pulseaudio, so you will need to consult it's documentation.

Hi,

I don't know how to do it with pulseaudio, however I have created such a setup using pure alsa. I documented it here : http://www.linuxquestions.org/questions ... agic-3645/
