Could you please be more specific in regards to headphones and HDMI not working? When you connect headphones, do the internal speakers get disabled, do you only hear audio from one headphone?
As to HDMI, did you try going into the volume control preferences and selecting the HDMI output from the audio profile dropdown list?
