No sound from LG monitor build-in speaker with MacBook Air M2 and Plugable UD-6950H

Hi, I just connected my MacBook Air M2 with Plugable UD-6950H and LG 4k monitor with build in speaker. The LG monitor is connected to Plugable via HDMi cable. I can see the video on LG but no sound can be selected/played from MacBook Air other than the MacBook build in speaker. Please let me know what I should do to make LG build in speaker work. Thanks
