I have a Framework 16 laptop, the AMD Ryzen 7040 series. From the default GhostBSD install I do get sound, but the sound controls were missing from the system tray area in XFCE. Having run into this issue before on Gentoo, I remembered it could sometimes be a missing package issue.
I went looking for the package and installed it:
$ sudo pkg install -y xfce4-mixer-full
That at least let me add the the sound controls to XFCE's system tray. Attempting to actually use the sound mixer results in an error.
GStreamer was unable to detect any sound devices.
This is odd, because I can pull up a YouTube video and get sound just fine, I just can't alter the volume. Any suggestions?
