Hello Mirko,

We only use tone_stream to generate busy tones, etc. ? there are no sound files on the server at all.

It's probably what Dragos mentioned (stereo calls) and this warning is caused when writing recordings into a single channel in the file.

The problem appeared suddenly and I conclude it's because they started to use Firefox instead of Chrome (Webrtc).

Even though the Opus codec string is "OPUS@8000h@20i@1c" which should be 1 channel, Firefox just uses stereo anyway apparently.

If I can't get Firefox to behave somehow, I will probably just squelch it on the log server :-/

Thanks...
/Allan

but I think:
https://freeswitch.org/stash/projects/FS/repos/freeswitch/browse/src/switch_core_file.c
is used for playing files from filesystem, into the channel, IVR or MOH,.... used by mod_localstream or by setting the MOH var on channel  in ivr_bridge when channel is on hold

Not sure if it can be triggered from more modules

You are getting stereo calls perhaps.

Hello,

We don't play any messages AFAIK, could it be related to recording?

looks like you are trying to play mono audio file from directory that has 

    <param name="channels" value="2"/> 

maybe in your local_stream.conf

Hello,

Out of nowhere we have started to get a lot of these:

[WARNING] switch_core_file.c:408 File has 1 channels, muxing to 2 channels will occur. 
[WARNING] switch_core_file.c:408 File has 1 channels, muxing to 2 channels will occur.  [WARNING] switch_core_file.c:408 File has 1 channels, muxing to 2 channels will occur. 

I've tried to look in the code for an explanation, without succes.

Does anyone know why this is appearing ?

Thank you,
