Subject: C-Media 8738 sound driver + A7M266-D problems.


I have a dual AMD board that has the 8738 onboard. I compile 2.4.18 and
pass it the '6 speaker' selection which should push the Rear speaker
signal out the Line In connector and the Center Speaker Out/ Sub-woofer
signal out the Mic In connector. This does not happen. I've tried this
as a module and passing the params on the command line as well as
compiling it directly into the kernel. Am I missing something (very
likely) or is this a known situation that I just have to deal with?

Is your app capable of writing 6 channel audio ?

Are you sure your hardware supports 6-channel output? There are
several version of the 8738 chip (with/without spdif, 4/6 channel).
The chip should read something like "CMI8738/PCI-6CH".

Furthermore, it requires some extra hardware (analog multiplexers, for
example a 4053) to switch the connections. Maybe the manufacturer
left that out (to save a few cents).

Hi,
I have the same motherboard at it include the hardware to support 6
speaker (and win2k support 6 channels)). I'm currently configuring
linux (gentoo with kernel 2.4.18) on my motherboard and don't yet
know about the rears chanels. I'll let you know.

Regards

You could try version 2.75a from http://download.asus.com.tw/mb_dl_menu.asp
