New installation of Zulu 3.4.0 on my Linux rig. Connection to the FreePBX server flawless but under “Audio Settings” all three options show empty and there is nothing to be selected.
Because of the covid-19 outbreak my office will start working from home next week and we need to select a softphone. If I can’t confirm the Zulu will be a plug and play solution we will be purchasing Bria instead.
I’m afraid you will need to spend sometime checking suse’s audio troubleshooting, will all your users use suse? with the same specs as your computer? can you try in another Linux installation or in a different hardware? I know it might seems to much to ask, I just want to determine if it’s an issue related with Zulu and your soundcard or Zulu and your OS/DE?
I’m afraid this is not as trivial as it might seem, as it might be several factors (kernel, module, misconfiguration of pulseaudio, etc), but now that we know is not a permission issue (which I don’t think it ever was) try deleting the directory ~/.config/pulse (make a backup first) and then logging out / in … to see if you have any audio on Zulu (check first that you have audio in your system after doing that)
Zulu has a Linux client, true, but it hasn’t been tested with all the combinations of hardware/kernels/linux distros and the desktop environments, as you might understand this will take forever.
