I've loaded the Mythtv distro called
KnoppMyth
The latest version has Linux kernel 2.6.15.chw-2.
I'm not sure what ALSA driver was in the kernel originally.
I've not had any luck fixing the sound driver for the onboard sound chip of the Asus A8N-VM CSM motherboard. The Asus motherboard manual says the sound chip is an AD1986a (Analog Devices, I believe).
I downloaded and compiled the ALSA drivers version 1.0.11rc4 per the instructions in the HOW-TO section of the ALSA website. It didn't help. The sound still does not work. This is even after using the mixer utility and unmuting all the audio channels.
Should the Plug And Play be turned on or off in the motherboard BIOS?
I have seen that there is a special sound patch file for the Analog Devices chips right in the ALSA driver directory structure. It's called "patch_analog.c". This file seems to be a specialized for the AD1986a chip. It calls it out in the top few lines of the code. There MUST be a way to get this file into the kernel so it will talk to the AD1986a properly. Does anyone know how ALSA drivers work? Do I need to patch this file into to something? If yes, could you give the commands and don't leave out any steps, please?
