Onboard Audio Help

[jvaldezjr]

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.

try running

alsamixer

and making sure there is not something muted

Done...still produces 2ch sound out of my front speakers, and no 5.1 sound.

Does Alsamixer show PCM, PCM Center, PCM Front, PCM LFE, PCM Side, PCM Surround?

[jvaldezjr]

It shows:

Master, Master Mono, PCM, Surround, Surround Jack Mode, Center, LFE, Line, CD, Mic, Mic Boost, Mic Front, Mic Select, Phone, IEC958 [PCM],
IEC958 Playback AC97-SPSA, PC Speaker, Aux, Mono Out Select [Mic],
Channel Mode [6ch], Duplicate Front [Off], External Amplifier [Off].

The sound card is read as NVidia CK8S and the Chip is Realtek ALC850 rev 0

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.
