5 years ago Having the sound on the host is the expected behavior. The VNC protocol is used to get the access to the application's UI via a web browser and VNC doesn't support transporting the sound.
Hi Thank you for your hard work in creating this docker. I have been trying to use the your docker to open up a remote firefox session in my home network, but have been running into an issue where sound is not coming across to the remote machine even though sound is enabled on the host computer. On the remote computer I will connect to the host in a browser using the URL http://192.168.1.222:5800. The inner firefox browser will come up. In the inner firefox browser I then will type the URL youtube.com. I will then select a link on youtube to play a video. The video plays correctly, however the audio plays on my host computer instead of the remote computer. Is there anything missing from my configuration? Here is my configuration
