Description
Capture Card: Dvico FusionHDTV5 RT Gold
Motherboard: Abit AB9 Quad GT
CPU: Intel 2.4GHz Quad-core
Distribution: Ubunutu 7.04 64-bit
Audio device: /dev/dsp
Video device: /dev/video0
Using as an anolog device.
mythtv version: 0.20.2 (proposed ubuntu 7.04 package)
Description: I have the audio from the capture card plugged in to the cd-in on the motherboard. Using TvTime? or XawTV, I have no problems with audio and video. Using mythtv, I have two situations when changing options on alsamixer:
- Set cd-in mute and capture I get no audio using mythtv. Recorded shows have no audio.
- Set cd-in unmute and capture, I get no audio using mythtv until I change the channel. After changing the channel, the audio is 7-8 seconds out of sync. Trying to sync using 'm' key will not work. Additionally, video becomes laggy on my quad-core/8GB RAM/Raptor HD computer. Eventually, mythtv reports an error with the video.
Best Guess: the audio is not being caputured properly by mythtv during situation #1. This is the correct configuration for alsa as described by the mythtv help on audio found here http://www.mythtv.org/docs/mythtv-HOWTO-7.html.

I have fixed my setup so that the audio is in sync with the video in mythtv. However, the problem of having to change the channel to get audio is still present. Below is a my amixer to get the capture settings correct.
I still must change the channel before hearing audio. Please let me know how else I can debug this problem.
