RE: No sound in Chrome [SEC=UNCLASSIFIED]

[James Darbyshire <Ja...@eSafety.gov.au>]

Hi all,

I am using the docker containers to run guacd and guacamole on an AWS EC2 instance.

The sound doesn't work in Chrome or Safari when I connect through Guacamole - the windows VM says "No audio output device is installed.".

When I connect using the Microsoft RDP client, sound works.

The following log messages are shown in guacd:

Is there a way to get audio working through Guacamole?

When I connect with IE 11 I get the following log message:

guacd[1421]: INFO:No available audio encoding. Sound disabled.

This leads me to think that Chrome and Safari both support the audio, but somehow they are not being recognised through Guacamole.

Regards,

James
