It's been about a year since the AMD Ryzen 5 2400G APUs have arrived, along with the Ryzen 3 2200G series.

I am wondering if it is still too soon to plan to purchase/build a system to use with LinHES.
I see the ASRock DeskMini A300 Series might even be a good back-end or front-end.

I would plan to stick with the HD HomeRun tuners.

I know there are reports Linux 4 19 or newer seem to have things stable for these APUs.

Any input, thoughts would be appreciated.

Thanks

With all the sales on the AMD Ryzen products, I did purchase the following:

AMD Ryzen 5 2400G
Gigabyte B450I Aorus Pro WiFi mini-iTX
(2) 8GB Ballistix Sport LT DDR4-3200 RAM

Would like to see if it can run on LinHES 8.6.1,

I am trying to determine if it will work with the current linux kernel version on LinHES 8.6.1
At least I hope it will be a fun experiment.
I am getting Video but no audio from the HDMI port

I reviewed the ArchLinux installation guide, which only provide installing Arch, but not configuring video.

I do see
/lib/modules/4.9.159-1-ARCH/kernel/drivers/gpu/drm/amd/amdgpu/amdgpu

But I am not finding the
xf86-video-amdgpu

Running:
pacman -Ss xf86-video
Code:
core/xf86-video-ati 1:18.0.1-1 (xorg-drivers)
    X.org ati video driver
core/xf86-video-intel 1:2.99.917+860+g3a2dec17-1 (xorg-drivers)
    X.org Intel i810/i830/i915/945G/G965+ video drivers
core/xf86-video-vesa 2.4.0-1 (xorg-drivers xorg) [installed]
    X.org vesa video driver
core/xf86-video-vmware 13.2.1-2 (xorg-drivers)
    X.org vmware video driver


So i've been spinning myself around in trying to determine if:
1. I have a slight chance of getting this to work.
2. If so, do I need to get the xf86-video-amdgpu even though I found
/lib/modules/4.9.159-1-ARCH/kernel/drivers/gpu/drm/amd/amdgpu/amdgpu

Any input will be appreciated.

I don't have a solid answer for you, but I believe with an nvidia card, I had to follow instructions here to get sound to work outside of mythtv:
https://wiki.archlinux.org/index.php/Ad ... s_not_work

You can use aplay -l to figure out what audio devices alsa thinks you have and check whether you can force any audio from the command line. If so, I would think it is just a mythtv frontend configuration issue. If not, then I suspect it would be more likely a driver/support issue.
