It output correct values for first channel peak -350 and rms -700 dB. But for second channel it send most of the time peak -24.643 and rms -61.0874 dB but it can go higher. Sometimes it output correct values -350/-700. When I put audiotestsrc wave=silent it is consistent -350/-700 for both channels.<br> </p> <p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;"><br> Device for pulsesrc is set to null-sink monitor so there should be total silence which should be true because I don't hear anything and when I open the recoreded sound in audacity it is also stright line.<br> </p> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <style type="text/css"> p, li { white-space: pre-wrap; } </style> </body> </html>
