[mythtv-users] No Display

[Andy]

Well that is a great idea... in theory.  I tried this a couple of different ways... I paused a YouTube clip, and I tried playing a 10 second silence clip on loop in audacious and in VLC.
When I do that, I can "see" the desktop and/or the mythtv frontend. But when I try to play a clip, I get an error saying: "Potential ALSA version problem; [the program] failed to initialize your sound output device (if any).  Please update alsa-lib to version 1.0.23-2-g8d80d5f or higher to try to fix this issue"
I am running mythtv v. 0.24, so I assume this error message is occurring because the ALSA mixer is occupied with whatever was playing.
Also is it weird that the TV continues to recognize the signal even when a clip is paused?

Thanks for all the helpful advice. I have become convinced, however,
that my problem is a problem with the television as suggested by Greg
and Jay. If anyone knows how to get the audio signal "always on"
either through Xorg.conf or ALSA, I would appreciate a nudge in the
right direction.

This is why I am sure that it is not a problem with the resolution:
- Video comes on with any audio signal from any source (including when
I play a YouTube through Firefox), which I surmise means that there is
no change in the resolution of the video signal.
- I changed my audio settings (through the very cool new "scan for
audio" feature) to put audio out to a boombox. The audio came through
fine, but the video signal did NOT switch on. Which again leads me to
believe, as Greg and Jay suggested, that the TV will not display
without both audio and video streams over HDMI.

Hopefully I can get some help with TV settings from LG, other wise the
easy solution will be to return it for a model that DOES display HDMI
without an audio signal. I will be carrying my mythtv box with me and
demanding to hook it up before I purchase another TV. Or again, if
anyone knows how to get the audio signal "always on" either through
Xorg.conf or ALSA, I would appreciate the help.

Well, it's tacky as hell, but "when in doubt, use brute force":

You could always set audiacious to start at boot, and loop-play a 10 second clip of silence.  :-)  (Or, I guess, just aplay in a while true loop in a
shellscript.)
