<div>Hi,</div>
<div><br>
</div>
<div>do you have a loopback from
rtpsink.monitor to your default sink? The null sink<br>
just discards the audio.</div>
<div>pactl load-module module-loopback
source=rtpsink.monitor<br>
</div>
<div><br>

<div>Regards</div>

There is another SIP speaker that receives the multicast but
not my PC.</div>
