Horizon 8.0 - RHEL 8.2 guest - No sound

Jump to solution

Hi,

I have a virtual desktop with RHEL 8.2 running Horizon Agent for Linux 8.0, i connect to the virtual desktop with the latest horizon client and i get no sound.

If i go to GNOME sound settings i see only an output device called Dummy Output.

Anyone had similar problem? Any fix?

If there is no such line, just add follow line to MonitorAudio.sh and startBlastWorker.sh, and have a try.

export SSH_CONNECTION=""

Is this a new issue for 8.x Linux Agent? or have you tried the case on 7.x Linux Agent?

Could you please run below commands and collect command output at connected desktop terminal:

# pax11publish -d

# pactl info

# ls -l <Each_subpath_at_Server_string> (Server string can be seen at output of pax11publish -d command, like ls -l /run/user/1002, ls -l /run/user/1002/.vmwblastaudio:101, ls -l /run/user/1002/.vmwblastaudio:101/native)

Hi,

Thanks for the feedback. Could you please try below things? thanks.

1. Disable the selinux by the command "# setenforce 0", and try again.

2. If step 1 does not work, try to run follow command, and collect output

/usr/bin/start-pulseaudio-x11
# pax11publish -d

3. Collect Linux agent log file by command "# /usr/lib/vmware/viewagent/bin/dct-debug.sh"

1. selinux was disabled:

getenforce
Disabled

 

2. There was no /usr/bin/start-pulseaudio-x11, then i looked for the package containing that binary and its pulseaudio-module-x11 which was not installed, so i installed it and rebooted the desktop, but still no sound.

 

But now "pax11publish -d" has output:

Hi,

Could you install Linux agent again after yum install pulseaudio-module-x11 package, and to see whether it's ok.

If it still does not work, please help to re-run pax11publish command, and run "ls -la <each_server_path>", I saw  you only run "ls -a" command, thanks a lot.

also when i run  start-pulseaudio-x11 i get error:

Failure: Module initialization failed

 

Haa, but this seems because was already running... if i kill all pulseaudio processes and then run start-pulseaudio-x11 it starts ok.

But still no audio.

Please try to edit /usr/lib/vmware/viewagent/bin/MonitorAudio.sh with root.

Search line: if version_ge "${DISTRO_RELEASE}" "8.3"; then

Then update "8.3" to "8.2", logout and connect to desktop again. If it's lucky, audio shall be able to work now.

If it does not work, please continue to run follwing commands and collect output:

# ls -la <server_string_path>

# sudo /usr/lib/vmware/viewagent/bin/MonitorAudio.sh

Hi,

The thing looks normal now, as the "native" file is created. Perform one logout, and connect to desktop, neither audio out or audio in works, right? Do you install viewagent with option "-a yes"?

If logout does not work, please try to reboot vm, and do one connection, to see the result.

If still not working, Please run ls -la for each subfolder for server path:

# pax11publish -d: to get the server path

# ls -la /run/user/

# ls -la /run/user/1001/

#ls -la /run/user/1001/.vmwblastaudio:100/

After reboot i have sound!

 

Thank you so much for the help, so the fix was adding the line

export SSH_CONNECTION=""

and then reboot.
