 ====== Mini PC AMD Ryzen 7 5825U Acemagician AM06PRO ======
-===== Problem with Pulseaudio and ALSA =====
+I purchased this Mini PC to do video editing using the **Olive Video Editor** program. My previous Mini PC based on the Intel N95 **was not able to playback 2.7K/60 fps videos**, it only does 1080/30 fps. The **AMD Ryzen 7 5825U** CPU is instead  capable of previewing the clips applying cropping on the fly on Olive, which is what I actually need.

+===== Linux kernel support of WiFi adapter =====
+GNU/Linux **kernel 6.1.0** shipped with **Debian 12 Bookworm** does not support the WiFi adapter FIXME.
+===== Problem with audio over HDMI using Pulseaudio and ALSA =====
+I had a problem getting audio to work on the **HDMI port**: at bootstrap the PC was totally mute; **no audio** was routed to the HDMI display.
+First of all I manually checked all the following:
+  * Unmute the **S/PDIF output** using **alsamixer**.
+  * Opened the XFCE mixer app **pavucontrol**:
+    * Into the **Output Devices** tab check that the HDMI #1 is unmuted and //Set as fallback//.
+    * FIXME: Check the the pavucontrol uses the correct master volume...
+    * Start an audio player (e.g. the **audacious** program to play some mp3 files); into the **Playback** tab of pavucontrol check that the app is using the **HDMI #1** port to route the sound.
+Now you should ear the sound coming from the HDMI display (obviously your device must have the speakers!).
