Search the archives of that list for details. As far as I know there is no fix yet. What I found was that setting the audio input on the command line with ivtvctl fixes the issue, temporarily. Something like: </DIV> <DIV> </DIV> <DIV>ivtvctl -d /dev/video1 -q 1</DIV> <DIV> </DIV> <DIV>Check the manual for ivtvctl and make sure the parameters are correct. I have a script that runs every minute via cron and loops for 55 seconds running this command every 5 seconds. Kinda lame but it works for me.<BR clear="all"></DIV></BLOCKQUOTE></DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>You're right, it might be the "tinny" audio problem, hard to tell with all the subjective terms used to describe it, but it's always been hard for humans to describe sound in words.</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>One possible workaround: Try connecting the RF feed into the 150 and the baseband feed into the 350, if there is no other reason you need to have them the way they are. </DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>This might well mask the problem unless the OP is unlucky enough to have two cards with the same problem.</DIV></BODY></HTML>
