Okay, so what did it take to get the ATI TV Wonder Pro running on Gentoo Linux with sound and video under MythTV, you ask? You ask the weirdest questions sometimes:
- Upgrade the kernel to 2.6.10 (unstable for AMD64)
- Patch the kernel with the latest Video-for-Linux patches for that kernel version, which include fixes for cx8800 audio. These are simple .diff files that you just run against the kernel in
- Now rebuild the kernel, (copy the old .config over first)
genkernel --oldconfig --menuconfig all
- Mute (M) and select (space) "Line" in alsamixer. Mute the microphone (feedback otherwise). Set "Capture" to 100% and select it. Use
alsactl storeto store the results when you're done.
- Then, run
v4lctl volume mute offto un-mute the (by default muted) sound channel. TVTime doesn't require this step, just MythTV (I guess TVTime explicitly un-mutes).
- Running with TVTime requires un-muting the Line.
I can't imagine most non-technical users ever having got through all the steps required to get us here, but the kernel patching should fold in fairly soon. The need for the v4lctl call seems like a simple bug in MythTV. The ALSA settings are non-obvious... it would be useful to have that all auto-configure when Myth detects the ATI TV Wonder Pro.
