I had to do this for the analog side of my Hauppauge HVR-2250.<br><br><br></blockquote><div><br></div><div><br></div><div>If your card is indeed video1 instead of video0, then the next thing is to find out the range you can give it to do set-ctrl. I am not sure of the syntax for finding the settings, but the man page for v4l2-ctl will show you how to find the numeric range to use. For my HVR-2250, the range was -50 to +50 I believe. I set my volume to -5 with good results. Check to see what the range is for yours before using -5.</div><div><br></div><div>Regards</div></div></div><br>-----Inline Attachment Follows-----<br><br><div class="plainMail">_______________________________________________<br>mythtv-users mailing list<br><a ymailto="mailto:mythtv-users@mythtv.org"
