Hello, I have an Inspiron 2350. When I have HDMI out connected to a projector I have no audio. There is no audio through HDMI or through the headphone jack. I have made sure that mute is off. My need is to go from PC to projector then a 1/8th" to a external audio monitor or come out the headphone jack on the pc. Right now I am unable to do either. When a HDMI cable is connected I have no audio out.
Right click the speaker or sound icon on the taskbar, click Devices. You should see something like this =
Right click the white area and check both choices. Now post a screenshot of yours.
