No Audio on Rocky Linux 8

[artjail_office]

Hello,

We're having trouble getting Audio to work with HP ZCentral Remote Boost Sender 20.4.1 on Rocky Linux 8.10.

ERROR - PulseRecorder::createPulseSession: Failed to create pulse audio session: unable to connect context.
ERROR - PulseRecorder::createPulseRecordStream - pulse connection failed

We have tried both pulseaudio and alsa in the configuration, for example:

Rgsender.Audio.Linux.RecorderApi=alsa
Rgsender.Audio.Linux.DeviceName=plughw:0,0
or
Rgsender.Audio.Linux.RecorderApi=pulseaudio
Rgsender.Audio.Linux.DeviceName=alsa_output.pci-0000_00_1b.0.analog-stereo.monitor

The pulseaudio daemon is running and I can't find any other information on how to troubleshoot the errors.
Thank you!

Here are some things that should make Pulse Audio work.  Now we did address this in the latest release V22.1.2.9453 and V20.4.2.9063.  Addressed an issue where the RHEL Linux Sender installer did not list a required package as a dependency for remoting audio.

You will need these:

pulseaudio-utils
pulseaudio-libs
xorg-x11-utils

The use the script that is in Remote Boost to change to Pulse Audio.

Change the properties

script rg_alsaconfig
/opt/hpremote/rgsender/audio

Can be used to revert any changes
Run script without any options

HP Remote Boost Audio Configuration script

To use ALSA audio, use the command:
rg_alsa_config.sh alsa
To use ALSA audio and capture at 48K, use the command:
rg_alsa_config.sh alsa 48
To reset to default audio config, using PULSE, run the command:
rg_alsa_config.sh reset

If you still have problems, or would like the latest release, especially if  you need V20.4.2, you will need to contact me at zcentral@hp.com

Hi Kelly,

Thank you so much for the information.
I did make sure to have all those packages installed and have tried both pulse and alsa configuration.
So we should probably try the latest version 20.4.2 next and I emailed you. I just figured I'd reply here as well if anyone else stumbles upon this issue.

Hi Kelly,

The latest version in combination with setting the capture rate to 48K did the trick. Appreciate your help 🙂
