    Onboard Audio Help


    I have a EPoX motherboard that has 8 channel Realtek audio onboard. My problem is that when I hook up all the audio cables, it sounds like I only have 2 channel sound, instead of 5.1. I'm running Ubuntu Hoary, with the 2.6.10-5-386 kernel, trying to use ALSA as my sound engine under KDE. I've been able to install the Realtek driver package and updated ALSA to 1.0.9- but it still sounds like I have damn 2 channel audio. It's niot recognizing that I have an 8 channel onboard audio controller.

    Can anyone help? I've bounced around a few forums, and nothing so far.

    It looks like your card is not being recognized as being 5.1 capable. Here's a screenshot of how Alsamixer sees my Audigy 2 ZS.

    Right...my problem is getting my card recognized. I've got the drivers from Realtek installed, but still nothing and last I checked, my audio was supported on ubuntu's website.
