Surround Sound - CMedia 8768 - how do i get it going?


Hi

I have just bought a brand new Cmedia 8768 soundcard with a new set of speakers. I run a dual OS machine with both XP and SuSE 9.1 pro on it. In XP, the drivers installed fine and I had all 8 speakers blaring out. However, on a reboot into Linux, I only get 2 speakers working properly - the front left and front right. How do I get Linux to pick up my other 6 speakers? The module being used is cmipci on the ALSA sound system. Please simplify the answer - I'm quite new to Linux :P

check your mixer settings

Number one place to check is your mixer settings. Use alsamixer to open it up and check that nothing is muted or at 0 volume. The next step is to see what driver options you can pass to it to enable things. Should be in the documentation for that alsa module. Then you can add to the append line of lilo.conf if you need to set it up. But you'll most likely be passing it wherever the module is being loaded. HTH

The 3d sound option in the alsamixer could be a toggle. It's really deceptive since it looks like all the other sliders. You either have it on or off, there's no level to set on on a toggle.

I've looked at it, and the setting is definitely on even though I cant change any of the settings. Because if I press m, effectively turning the option off, I get no difference Would I have to tell the driver how many output channels it has? If so, where do I tell it this?
