No audio when using RGS

[AsiSudai]

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:

I'm sorry to see that there's been no response so far. I've been struggling with this as well, but with RemoteBoost v20 on Ubuntu 20.04. So far I have tried the same exact steps you have, following the official documentation as best I can. I suspect I'll need to read up on Pulse or ALSA documentation before I get any more movement with this.

Asi, is there any chance you were able to figure this out since your first post?

For audio on Ubuntu 20, we found an issue where audio wouldn't play and it is planned to be fixed in the next patch release of Remote Boost.

Thanks for chiming in, Becky. That's... weirdly, kind of a relief! Been banging my head on a wall for the past few hours, good to know I can stop.

Any sense of when the next release will be available?

Hi Becky.... Has the update to HP Boost with full audio support for Ubuntu 20LTS been released yet?

[runich]

I had a similar issue in CentOS7 albeit using Pulse audio and realised I was missing pulseaudio-module-x11.  Once installed  via yum -y install pulseaudio-module-x11 remote audio started working.  Perhaps this might provide a clue for you?

Cheers,

Rich
