#4001: Mythtv audio and Dvico FusionHDTV5 RT Gold
-----------------------+----------------------------------------------------
Reporter: anonymous | Owner: ijr
Type: defect | Status: new
Priority: minor | Milestone: unknown
Component: mythtv | Version: unknown
Severity: medium | Mlocked: 0
-----------------------+----------------------------------------------------
Capture Card: Dvico FusionHDTV5 RT Gold[[BR]]
Motherboard: Abit AB9 Quad GT[[BR]]
CPU: Intel 2.4GHz Quad-core[[BR]]
Distribution: Ubunutu 7.04 64-bit[[BR]]
Audio device: /dev/dsp[[BR]]
Video device: /dev/video0[[BR]]
Using as an anolog device.[[BR]]
mythtv version: 0.20.2 (proposed ubuntu 7.04 package)[[BR]]
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].
