<br>But the fact I do not have line in shoud just avoid hearing the live TV,<br>a thing that we do not want, anyway.<br><br>However, using mplayer, I can record the TV and playback the result with sound. In this case, I should not use the arecord stuff. As a matter of fact, I just do no hear anything while recording , but the resulting avi has sound.
<br><br>What makes me believe that the problem is OSS/Alsa in myth.<br>Since I have never looked myth code before, I do not know where to start.<br>Does recording use OSS only?<br><br>The relevant part of my mplayer script is below.
<br>Therefore, I can record live TV. But without myth, is like going back to the stone age again.<br><br>The environment variables from my script are not important:<br><br># sudo nice -n -19 \<br>mencoder tv://${CHN} \<br>
