I've got my mythtv almost working. Video records now, firewire is
connected to my STB and 6200ch is changing the channels. However, I
can't get the audio to record.
I have the audio out from my STB (RCA left/right) going to the 3.5mm
plug on my motherboard (line-in). I went to the sound preferences in
ubuntu (11.04), "input" tab, and chose my onboard audio chip, then the
"Analog line-in". I can see the audio meter working, so I know audio
is coming in on this input.
I tried the "Sound Recorder" program that came with Ubuntu, and that
records audio. However, when I schedule a recording in mythtv, I just
get no audio at all. I've played recordings back both with
mythfrontend (on the same machine), and downloaded & played on VLC on
my laptop. Neither has audio, though if I increase the volume a lot I
can hear the slightest noise, probably just the noise of the sound
card input itself.
I looked at the mythtv-setup for my tuner card, and it has
"ALSA:default" as the sound input. I've also used arecord and aplay
to record audio, and those work.
What's my next steps? How do I troubleshoot the lack of audio?
