I have a desktop computer with an AMD Ryzen 5 4650G PRO APU (CPU + on-die GPU). The motherboard (MSI Mortar B550m wifi / bios 1.6). has one displayport and one HDMI outputs. The displayport is connected to my Lenovo P27 monitor, and the HDMI to my Samsung TV.

When I choose the GPU as an audio out, I only get audio on the 3.5" headphones jack of the Lenovo monitor, while I would like to get the audio on the Samsung TV over HDMI. I can't find a way to switch the different outputs (neither over pipewire or just using native alsa).

pavucontrol configuration https://i.imgur.com/9nbVtNz.png alsamixer -c0 only has only one option to mute s/pdif, which mutes the output on the displayport -> Lenovo -> 3.5" jack.

Am I correct that card 1 here ^ should have at least two devices?
