<div>I ended up putting the following in my channel changing script:</div>
<blockquote dir="ltr" style="MARGIN-RIGHT: 0px">
<div>sleep 3</div></blockquote>
<blockquote dir="ltr" style="MARGIN-RIGHT: 0px">
<p>/usr/local/bin/v4l2-ctl --set-audio-input 1 -d /dev/video1 >/dev/null</p></blockquote>
<p> This is for S-Video, you may need to change the video device for composite</p>

<br>my cable box. Now I don't have a cable box anymore and I'm using the<br>tuner on the PVR-150 so I don't have this issue any more. I came<br>across this hack when I was trying to deal with the problem:<br>
<br>#!/bin/sh<br># Some variables used to remember if the device is in use or not<br>record_video0=NO<br># Loop forever<br>while true<br>do<br> # Is the video device in use ?<br> fuser /dev/video0 2>/dev/null >/dev/null
<br> if [ $? -eq 0 ]<br> then<br> # Something is using video device and this is the first time<br>we notice this<br> if [ "$record_video0" = "NO" ]<br> then<br> date<br> echo " recording on video0"
<br> sleep 5<br> /usr/local/bin/ivtvctl -d /dev/video0 -q 0<br> echo<br> fi<br> record_video0=YES<br> else<br> # Not recording<br> if [ "$record_video0" = "YES" ]
<br> then<br> date<br> echo " not recording anymore on video0"<br> echo<br> fi<br> record_video0=NO<br> fi<br> sleep 1<br>done<br><br>I put this in a script called sound_fixer and started this in my
<br>.xinitrc (or .xserverrc, I forget). You might have to play with the<br>"-q" value in the ivtvctl command to figure out which one works for<br>you.<br><br>Hope this helps,<br>Akshat<br>_______________________________________________
