Not used the DY-HV8F but have used something with a similar protocol though not with a Pico. Do you have a link to where you got your command info from, know what actual player chip it uses ?
Your UART configuration, command and checksum look correct to me compared to what I have used.
Could it simply be a lack of 0V/GND between the Pico and DY-HV8F ?
Maybe the file isn't in the correct place on SD Card, or is named wrongly ?
Maybe a 'time.sleep(5)' before the first '.write' will give the module time to initialise and enumerate ?
Maybe the Volume needs to be set ?
Perhaps issue a Status inquiry and see what comes back ?
