XDG_RUNTIME_DIR (/run/user/1000) is not owned by us (uid 0), but by uid 1000! (This could e.g. happen if you try to connect to a non-root PulseAudio as a root user, over the native protocol. Don't do that.) **** List of PLAYBACK Hardware Devices **** card 1: realtekrt5616co [realtek,rt5616-codec], device 0: fe470000.i2s-rt5616-aif1 rt5616-aif1-0 [fe470000.i2s-rt5616-aif1 rt5616-aif1-0] Subdevices: 1/1 Subdevice #0: subdevice #0 card 2: rockchiphdmi0 [rockchip,hdmi0], device 0: rockchip,hdmi0 i2s-hifi-0 [rockchip,hdmi0 i2s-hifi-0] Subdevices: 1/1 Subdevice #0: subdevice #0 card 3: rockchipdp0 [rockchip,dp0], device 0: rockchip,dp0 spdif-hifi-0 [rockchip,dp0 spdif-hifi-0] Subdevices: 1/1 Subdevice #0: subdevice #0 card 4: rockchiphdmi1 [rockchip,hdmi1], device 0: rockchip,hdmi1 i2s-hifi-0 [rockchip,hdmi1 i2s-hifi-0] Subdevices: 1/1 Subdevice #0: subdevice #0
