<div class="moz-cite-prefix">For some reason at 48khz with
inbandfec=1 and dtx=0, if a packet is lost, Chrome sends
something, which triggers that FEC error and causes a robotic
sound. Once we either enabled DTX or explicitly disabled FEC, the
FEC errors vanished and the robotic voice was gone. I think the
RTCP errors were a separate issue.<br>
<br>
Thanks for the quick fix!<br>

Hi <br>
<br>
I have tested yesterday FS master
(b5e486fd5c9bfb52923b30b8b53037c39cdb8665) with Opus PLC
and I can tell
you that it works just fine .<br>
If there is/was a bug it must have been because of rtp
& rtcp
mux/demux , by looking at the<br>
error message about payload type. Do those errors show at
regular
intervals ? eg: 5 seconds , which can be the rtcp interval
? <br>
<br>
Regards,<br>
Dragos

When I test through echo without any
decoding, it sounds surprisingly
good for 5% packet loss. So it seems like
an FS issue. It's quite
strange though. Will file a jira.

<br>

That's accompanied by robotic

This sounds more like FS is
receiving total junk rather than
missing

be checksums<br>
preventing errors inside these

bug in FS,
or do I need an exorcist for
