Since we apply per-stream volumes before<br> we resample/remix it's a bit hard to give you the data unmodified.<br> <br> Instead of monitoring particular sinks you can also monitor<br> particular sink inputs, which will give you the data without the sink<br> volume applied. (but with the sink input volume applied). To do use<br> pa_stream_set_monitor_stream().<br> <div><div></div><div class="h5"><br> Lennart<br> <br> --<br> Lennart Poettering Red Hat, Inc.<br> lennart [at] poettering [dot] net<br> <a href="http://0pointer.net/lennart/" target="_blank">http://0pointer.net/lennart/</a> GnuPG 0x1A015CC4<br> _______________________________________________<br> pulseaudio-discuss mailing list<br> <a href="mailto:pulseaudio-discuss@mail.0pointer.de">pulseaudio-discuss@mail.0pointer.de</a><br> <a href="https://tango.0pointer.de/mailman/listinfo/pulseaudio-discuss" target="_blank">https://tango.0pointer.de/mailman/listinfo/pulseaudio-discuss</a><br> </div></div></blockquote></div><br><br clear="all"><br>-- <br>"Weekends don't count unless you spend them doing something completely pointless.
