Mythtv audio and Dvico FusionHDTV5 RT Gold

Reported by: anonymous Owned by: Isaac Richards
Priority: minor Milestone: unknown
Component: mythtv Version: unknown
Severity: medium Keywords: audio dvico fusionHDTV

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:

  1. Set cd-in mute and capture I get no audio using mythtv. Recorded shows have no audio.
  2. 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.
