Playing audio on a board requires selecting the sound output in the settings interface every time you restart. The default output is analog output, which is very troublesome. I have tried to modify the file in/etc/pulse/, but it did not work. How can I modify it so that HDMI output is the default sound output after each reboot.
please try this.
pacmd list-sinks for name or index number of possible sinks
pacmd list-sources for name or index number of possible sources
pacmd set-default-sink "SINKNAME" | index to set the default output sink
pacmd set-default-source "SOURCENAME" | index to set the default input
vim /etc/pulse/default.pa
set-default-sink <*output device name>
It’s working properly now
