Hello,

I'm unable to hear audio from the remote machine when using RGS. For example playing an audio file or using Firefox, neither will play audio through RGS.

I'm using Windows-10 to RGS into a CentOS-7 through a VPN.

The CentOS-7 has HP Remote Graphics Sender Version: 7.6.1.19438  |  Build Date: Apr 5 2019 installed.
The Windows-10 has  HP Remote Graphics Receiver  Version: 7.7..0.20876 |  Build Date: Apr 5 2019 installed.


Things we tried but didn't work:
- set rgsenderconfig:
Rgsender.Audio.IsEnabled=1
Rgsender.Audio.Linux.RecorderApi=alsa
Rgsender.Audio.Linux.DeviceName=plughw:0,0
- Enabled logging Rgsender.Log.Filename=rg.log



Sender Log:
