The last app to access the card was a reboot, had major power failure
last night and the ups dropped off after about 20 mins.
So this is a fresh powerup reading taken from v4l-info's very verbose
output:
audio
VIDIOCGAUDIO
audio : 0
volume : 0
bass : 0
treble : 0
Now, fire up tvtime... No diff, v4l-info still reports the same:
audio
VIDIOCGAUDIO
audio : 0
volume : 0
bass : 0
treble : 0
As far as tvtime.xml is concerned, the newest one by about a month is
the one in /root/.tvtime/tvtime.xml:
<?xml version="1.0"?>
<!DOCTYPE tvtime PUBLIC "-//tvtime//DTD tvtime 1.0//EN"
"http://tvtime.sourceforge.net/DTD/tvtime1.dtd";>
<tvtime xmlns="http://tvtime.sourceforge.net/DTD/";>
<option name="DefaultBrightness" value="50"/>
<option name="DefaultContrast" value="50"/>
<option name="DefaultColour" value="100"/>
<option name="DefaultHue" value="50"/>
<option name="Norm" value="NTSC"/>
<option name="PrevChannel" value="7"/>
<option name="Channel" value="48"/>
<option name="FramerateMode" value="0"/>
<option name="OverScan" value="3.5"/>

<option name="ColourInvert" value="0"/>
<option name="DeinterlaceMethod" value="TelevisionFull"/>
<option name="NTSCCableMode" value="IRC"/>
<option name="Frequencies" value="us-cable"/>
</tvtime>
The only reference to audio can be seen above. Do I need to add
something? I've searched thru the menu's, but there is not much
about the audio there.
There is another tvtime.xml, but it appears to be the default source,
listing all the help hints etc that do not seem to have been written
out into the operational file in /root/.tvtime/
Humm, my locate also spit out a manpage, which I have not yet studied,
dumb...
I note that it puts a fairly heavy hit on the cpu, around 35-40%, is
there some option to turn on dma or something to alleviate that?
