It depends on the software some will use the HDMI port others may use the headphones you need to configure the software.

What application are you using??

Try the configuration option
hdmi-drive=1
This is used for DVI monitors that do not support audio. The sound should be sent to the audio port instead of the HDMI port.

For instructions, see
